According to the version of the bind packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :

  - A buffer overflow flaw was found in the SPNEGO     implementation used by BIND. This flaw allows a remote     attacker to cause the named process to crash or     possibly perform remote code execution. The highest     threat from this vulnerability is to confidentiality,     integrity, as well as system     availability.(CVE-2020-8625)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote AlmaLinux 8 host has packages installed that are affected by a vulnerability as referenced in the ALSA-2021:0670 advisory.

  - BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG     features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed,     but a server can be rendered vulnerable by explicitly setting valid values for the tkey-gssapi-keytab or     tkey-gssapi-credentialconfiguration options. Although the default configuration is not vulnerable, GSS-     TSIG is frequently used in networks where BIND is integrated with Samba, as well as in mixed-server     environments that combine BIND servers with Active Directory domain controllers. The most likely outcome     of a successful exploitation of the vulnerability is a crash of the named process. However, remote code     execution, while unproven, is theoretically possible. Affects: BIND 9.5.0 -> 9.11.27, 9.12.0 -> 9.16.11,     and versions BIND 9.11.3-S1 -> 9.11.27-S1 and 9.16.8-S1 -> 9.16.11-S1 of BIND Supported Preview Edition.
    Also release versions 9.17.0 -> 9.17.1 of the BIND 9.17 development branch (CVE-2020-8625)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of AOS installed on the remote host is prior to 5.19.2. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.19.2 advisory.

  - Net-SNMP through 5.8 has Improper Privilege Management because SNMP WRITE access to the EXTEND MIB     provides the ability to run arbitrary commands as root. (CVE-2020-15862)

  - Sudo before 1.9.5p2 contains an off-by-one error that can result in a heap-based buffer overflow, which     allows privilege escalation to root via sudoedit -s and a command-line argument that ends with a single     backslash character. (CVE-2021-3156)

  - A heap-based buffer overflow was found in the way sudo parses command line arguments. This flaw is     exploitable by any local user who can execute the sudo command without authentication. Successful     exploitation of this flaw could lead to privilege escalation.  (CVE-2021-3156)

Affects: BIND 9.5.0 -> 9.11.27, 9.12.0 -> 9.16.11,     and versions BIND 9.11.3-S1 -> 9.11.27-S1 and 9.16.8-S1 -> 9.16.11-S1 of BIND Supported Preview Edition.
    Also release versions 9.17.0 -> 9.17.1 of the BIND 9.17 development branch (CVE-2020-8625)

  - The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking     vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on     a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value     remains the same starting from boot time, and can be inferred by an attacker. This affects     net/core/flow_dissector.c and related code. (CVE-2019-18282)

  - A buffer over-read flaw was found in RH kernel versions before 5.0 in crypto_authenc_extractkeys in     crypto/authenc.c in the IPsec Cryptographic algorithm's module, authenc. When a payload longer than 4     bytes, and is not following 4-byte alignment boundary guidelines, it causes a buffer over-read threat,     leading to a system crash. This flaw allows a local attacker with user privileges to cause a denial of     service. (CVE-2020-10769)

  - A memory out-of-bounds read flaw was found in the Linux kernel before 5.9-rc2 with the ext3/ext4 file     system, in the way it accesses a directory with broken indexing. This flaw allows a local user to crash     the system if the directory exists. The highest threat from this vulnerability is to system availability.
    (CVE-2020-14314)

  - A flaw was found in the Linux kernel before 5.9-rc4. A failure of the file system metadata validator in     XFS can cause an inode with a valid, user-creatable extended attribute to be flagged as corrupt. This can     lead to the filesystem being shutdown, or otherwise rendered inaccessible until it is remounted, leading     to a denial of service. The highest threat from this vulnerability is to system availability.
    (CVE-2020-14385)

  - In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new     filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the     current umask is not considered. (CVE-2020-24394)

  - A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers     to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c     instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452. (CVE-2020-25212)

  - A flaw was found in the HDLC_PPP module of the Linux kernel in versions before 5.9-rc7. Memory corruption     and a read overflow is caused by improper input validation in the ppp_cp_parse_cr function which can cause     the system to crash or cause a denial of service. The highest threat from this vulnerability is to data     confidentiality and integrity as well as system availability. (CVE-2020-25643)

  - The iconv feature in the GNU C Library (aka glibc or libc6) through 2.32, when processing invalid multi-     byte input sequences in the EUC-KR encoding, may have a buffer over-read. (CVE-2019-25013)

  - The GNU C Library (aka glibc or libc6) before 2.32 could overflow an on-stack buffer during range     reduction if an input to an 80-bit long double function contains a non-canonical bit pattern, a seen when     passing a 0x5d414141414141410000 value to sinl on x86 targets. This is related to     sysdeps/ieee754/ldbl-96/e_rem_pio2l.c. (CVE-2020-10029)

  - sysdeps/i386/ldbl2mpn.c in the GNU C Library (aka glibc or libc6) before 2.23 on x86 targets has a stack-     based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with     a non-canonical bit pattern, as seen when passing a \x00\x04\x00\x00\x00\x00\x00\x00\x00\x04 value to     sprintf. NOTE: the issue does not affect glibc by default in 2016 or later (i.e., 2.23 or later) because     of commits made in 2015 for inlining of C99 math functions through use of GCC built-ins. In other words,     the reference to 2.23 is intentional despite the mention of Fixed for glibc 2.33 in the 26649 reference.
    (CVE-2020-29573)

  - Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Serialization).

This vulnerability does not apply to Java deployments, typically in     servers, that load and run only trusted code (e.g., code installed by an administrator). (CVE-2020-14803)

  - Use-after-free vulnerability in fs/block_dev.c in the Linux kernel before 5.8 allows local users to gain     privileges or cause a denial of service by leveraging improper access to a certain error field.
    (CVE-2020-15436)

  - A flaw incorrect umask during file or directory modification in the Linux kernel NFS (network file system)     functionality was found in the way user create and delete object using NFSv4.2 or newer if both     simultaneously accessing the NFS by the other process that is not using new NFSv4.2. A user with access to     the NFS could use this flaw to starve the resources causing denial of service. (CVE-2020-35513)

  - When responding to new h2c connection requests, Apache Tomcat versions 10.0.0-M1 to 10.0.0, 9.0.0.M1 to     9.0.41 and 8.5.0 to 8.5.61 could duplicate request headers and a limited amount of request body from one     request to another meaning user A and user B could both see the results of user A's request.
    (CVE-2021-25122)

  - The fix for CVE-2020-9484 was incomplete. When using Apache Tomcat 10.0.0-M1 to 10.0.0, 9.0.0.M1 to     9.0.41, 8.5.0 to 8.5.61 or 7.0.0. to 7.0.107 with a configuration edge case that was highly unlikely to be     used, the Tomcat instance was still vulnerable to CVE-2020-9494. Note that both the previously published     prerequisites for CVE-2020-9484 and the previously published mitigations for CVE-2020-9484 also apply to     this issue. (CVE-2021-25329)

  - Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular     expression quantifiers have an integer overflow. (CVE-2020-10543)

  - Perl before 5.30.3 has an integer overflow related to mishandling of a PL_regkind[OP(n)] == NOTHING     situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction     injection. (CVE-2020-10878)

  - regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of     recursive S_study_chunk calls. (CVE-2020-12723)

  - The X.509 GeneralName type is a generic type for representing different types of names. One of those name     types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different     instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both     GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a     possible denial of service attack. OpenSSL itself uses the GENERAL_NAME_cmp function for two purposes: 1)     Comparing CRL distribution point names between an available CRL and a CRL distribution point embedded in     an X509 certificate 2) When verifying that a timestamp response token signer matches the timestamp     authority name (exposed via the API functions TS_RESP_verify_response and TS_RESP_verify_token) If an     attacker can control both items being compared then that attacker could trigger a crash. For example if     the attacker can trick a client or server into checking a malicious certificate against a malicious CRL     then this may occur. Note that some applications automatically download CRLs based on a URL embedded in a     certificate. This checking happens prior to the signatures on the certificate and CRL being verified.
    OpenSSL's s_server, s_client and verify tools have support for the -crl_download option which implements     automatic CRL downloading and this attack has been demonstrated to work against those tools. Note that an     unrelated bug means that affected versions of OpenSSL cannot parse or construct correct encodings of     EDIPARTYNAME. However it is possible to construct a malformed EDIPARTYNAME that OpenSSL's parser will     accept and hence trigger this attack. All OpenSSL 1.1.1 and 1.0.2 versions are affected by this issue.
    Other OpenSSL releases are out of support and have not been checked. Fixed in OpenSSL 1.1.1i (Affected     1.1.1-1.1.1h). Fixed in OpenSSL 1.0.2x (Affected 1.0.2-1.0.2w). (CVE-2020-1971)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of AOS installed on the remote host is prior to 6.0. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.0 advisory.

  - Vulnerability in the Java SE, Java SE Embedded, Oracle GraalVM Enterprise Edition product of Oracle Java     SE (component: Libraries). Supported versions that are affected are Java SE: 7u291, 8u281, 11.0.10, 16;

  - An issue was discovered in the Linux kernel through 5.11.3. A kernel pointer leak can be used to determine     the address of the iscsi_transport structure. When an iSCSI transport is registered with the iSCSI     subsystem, the transport's handle is available to unprivileged users via the sysfs file system, at     /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When read, the show_transport_handle function (in     drivers/scsi/scsi_transport_iscsi.c) is called, which leaks the handle. This handle is actually the     pointer to an iscsi_transport struct in the kernel module's global variables. (CVE-2021-27363)

  - An issue was discovered in the Linux kernel through 5.11.3. drivers/scsi/scsi_transport_iscsi.c is     adversely affected by the ability of an unprivileged user to craft Netlink messages. (CVE-2021-27364)

  - An issue was discovered in the Linux kernel through 5.11.3. Certain iSCSI data structures do not have     appropriate length constraints or checks, and can exceed the PAGE_SIZE value.

A use-after-free memory flaw was found in the perf subsystem     allowing a local attacker with permission to monitor perf events to corrupt memory and possibly escalate     privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as     system availability. (CVE-2020-14351)

  - In the Linux kernel through 5.8.7, local attackers able to inject conntrack netlink configuration could     overflow a local buffer, causing crashes or triggering use of incorrect protocol numbers in     ctnetlink_parse_tuple_filter in net/netfilter/nf_conntrack_netlink.c, aka CID-1cc5ef91d2ff.
    (CVE-2020-25211)

  - A flaw was found in the Linux kernel in versions before 5.9-rc7. Traffic between two Geneve endpoints may     be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE     tunnel allowing anyone between the two endpoints to read the traffic unencrypted. The main threat from     this vulnerability is to data confidentiality. (CVE-2020-25645)

  - A flaw was found in the Linux kernel. A use-after-free was found in the way the console subsystem was     using ioctls KDGKBSENT and KDSKBSENT. A local user could use this flaw to get read memory access out of     bounds. The highest threat from this vulnerability is to data confidentiality. (CVE-2020-25656)

  - A flaw in ICMP packets in the Linux kernel may allow an attacker to quickly scan open UDP ports. This flaw     allows an off-path remote attacker to effectively bypass source port UDP randomization. Software that     relies on UDP source port randomization are indirectly affected as well on the Linux Based Products     (RUGGEDCOM RM1224: All versions between v5.0 and v6.4, SCALANCE M-800: All versions between v5.0 and v6.4,     SCALANCE S615: All versions between v5.0 and v6.4, SCALANCE SC-600: All versions prior to v2.1.3, SCALANCE     W1750D: v8.3.0.1, v8.6.0, and v8.7.0, SIMATIC Cloud Connect 7: All versions, SIMATIC MV500 Family: All     versions, SIMATIC NET CP 1243-1 (incl. SIPLUS variants): Versions 3.1.39 and later, SIMATIC NET CP 1243-7     LTE EU: Version (CVE-2020-25705)

  - In drivers/target/target_core_xcopy.c in the Linux kernel before 5.10.7, insufficient identifier checking     in the LIO SCSI target code can be used by remote attackers to read or write files via directory traversal     in an XCOPY request, aka CID-2896c93811e3. For example, an attack can occur over a network if the attacker     has access to one iSCSI LUN. The attacker gains control over file access because I/O operations are     proxied via an attacker-selected backstore. (CVE-2020-28374)

  - A locking issue was discovered in the tty subsystem of the Linux kernel through 5.9.13.
    drivers/tty/tty_jobctrl.c allows a use-after-free attack against TIOCSPGRP, aka CID-54ffccbf053b.
    (CVE-2020-29661)

  - In the Linux kernel 4.14 longterm through 4.14.165 and 4.19 longterm through 4.19.96 (and 5.x before 5.2),     there is a use-after-free (write) in the i915_ppgtt_close function in drivers/gpu/drm/i915/i915_gem_gtt.c,     aka CID-7dc40713618c. This is related to i915_gem_context_destroy_ioctl in     drivers/gpu/drm/i915/i915_gem_context.c. (CVE-2020-7053)

  - A flaw was found in the way memory resources were freed in the unix_stream_recvmsg function in the Linux     kernel when a signal was pending. This flaw allows an unprivileged local user to crash the system by     exhausting available memory. The highest threat from this vulnerability is to system availability.
    (CVE-2021-20265)

  - When responding to new h2c connection requests, Apache Tomcat versions 10.0.0-M1 to 10.0.0, 9.0.0.M1 to     9.0.41 and 8.5.0 to 8.5.61 could duplicate request headers and a limited amount of request body from one     request to another meaning user A and user B could both see the results of user A's request.
    (CVE-2021-25122)

  - The fix for CVE-2020-9484 was incomplete. When using Apache Tomcat 10.0.0-M1 to 10.0.0, 9.0.0.M1 to     9.0.41, 8.5.0 to 8.5.61 or 7.0.0. to 7.0.107 with a configuration edge case that was highly unlikely to be     used, the Tomcat instance was still vulnerable to CVE-2020-9494. Note that both the previously published     prerequisites for CVE-2020-9484 and the previously published mitigations for CVE-2020-9484 also apply to     this issue. (CVE-2021-25329)

  - Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular     expression quantifiers have an integer overflow. (CVE-2020-10543)

  - Perl before 5.30.3 has an integer overflow related to mishandling of a PL_regkind[OP(n)] == NOTHING     situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction     injection. (CVE-2020-10878)

  - regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of     recursive S_study_chunk calls. (CVE-2020-12723)

  - In BIND 9.0.0 -> 9.11.29, 9.12.0 -> 9.16.13, and versions BIND 9.9.3-S1 -> 9.11.29-S1 and 9.16.8-S1 ->     9.16.13-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.11 of the BIND     9.17 development branch, when a vulnerable version of named receives a query for a record triggering the     flaw described above, the named process will terminate due to a failed assertion check. The vulnerability     affects all currently maintained BIND 9 branches (9.11, 9.11-S, 9.16, 9.16-S, 9.17) as well as all other     versions of BIND 9. (CVE-2021-25215)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote NewStart CGSL host, running version MAIN 6.06, has bind packages installed that are affected by multiple vulnerabilities:

  - By design, BIND is intended to limit the number of TCP clients that can be connected at any given time.
    The number of allowed connections is a tunable parameter which, if unset, defaults to a conservative value     for most servers. Unfortunately, the code which was intended to limit the number of simultaneous     connections contained an error which could be exploited to grow the number of simultaneous connections     beyond this limit. Versions affected: BIND 9.9.0 -> 9.10.8-P1, 9.11.0 -> 9.11.6, 9.12.0 -> 9.12.4, 9.14.0.
    BIND 9 Supported Preview Edition versions 9.9.3-S1 -> 9.11.5-S3, and 9.11.5-S5. Versions 9.13.0 -> 9.13.7     of the 9.13 development branch are also affected. Versions prior to BIND 9.9.0 have not been evaluated for     vulnerability to CVE-2018-5743. (CVE-2018-5743)

  - Controls for zone transfers may not be properly applied to Dynamically Loadable Zones (DLZs) if the zones     are writable Versions affected: BIND 9.9.0 -> 9.10.8-P1, 9.11.0 -> 9.11.5-P2, 9.12.0 -> 9.12.3-P2, and     versions 9.9.3-S1 -> 9.11.5-S3 of BIND 9 Supported Preview Edition. Versions 9.13.0 -> 9.13.6 of the 9.13     development branch are also affected. Versions prior to BIND 9.9.0 have not been evaluated for     vulnerability to CVE-2019-6465. (CVE-2019-6465)

  - A race condition which may occur when discarding malformed packets can result in BIND exiting due to a     REQUIRE assertion failure in dispatch.c. Versions affected: BIND 9.11.0 -> 9.11.7, 9.12.0 -> 9.12.4-P1,     9.14.0 -> 9.14.2. Also all releases of the BIND 9.13 development branch and version 9.15.0 of the BIND     9.15 development branch and BIND Supported Preview Edition versions 9.11.3-S1 -> 9.11.7-S1.
    (CVE-2019-6471)

  - A malicious actor who intentionally exploits this lack of effective limitation on the number of fetches     performed when processing referrals can, through the use of specially crafted referrals, cause a recursing     server to issue a very large number of fetches in an attempt to process the referral. This has at least     two potential effects: The performance of the recursing server can potentially be degraded by the     additional work required to perform these fetches, and The attacker can exploit this behavior to use the     recursing server as a reflector in a reflection attack with a high amplification factor. (CVE-2020-8616)

  - Using a specially-crafted message, an attacker may potentially cause a BIND server to reach an     inconsistent state if the attacker knows (or successfully guesses) the name of a TSIG key used by the     server. Since BIND, by default, configures a local session key even on servers whose configuration does     not otherwise make use of it, almost all current BIND servers are vulnerable. In releases of BIND dating     from March 2018 and after, an assertion check in tsig.c detects this inconsistent state and deliberately     exits. Prior to the introduction of the check the server would continue operating in an inconsistent     state, with potentially harmful results. (CVE-2020-8617)

  - In BIND 9.0.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.9.3-S1 -> 9.11.21-S1 of the     BIND 9 Supported Preview Edition, An attacker on the network path for a TSIG-signed request, or operating     the server receiving the TSIG-signed request, could send a truncated response to that request, triggering     an assertion failure, causing the server to exit. Alternately, an off-path attacker would have to     correctly guess when a TSIG-signed request was sent, along with other characteristics of the packet and     message, and spoof a truncated response to trigger an assertion failure, causing the server to exit.
    (CVE-2020-8622)

  - In BIND 9.10.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.10.5-S1 -> 9.11.21-S1 of the     BIND 9 Supported Preview Edition, An attacker that can reach a vulnerable system with a specially crafted     query packet can trigger a crash. To be vulnerable, the system must: * be running BIND that was built with
    --enable-native-pkcs11 * be signing one or more zones with an RSA key * be able to receive queries from     a possible attacker (CVE-2020-8623)

  - In BIND 9.9.12 -> 9.9.13, 9.10.7 -> 9.10.8, 9.11.3 -> 9.11.21, 9.12.1 -> 9.16.5, 9.17.0 -> 9.17.3, also     affects 9.9.12-S1 -> 9.9.13-S1, 9.11.3-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An     attacker who has been granted privileges to change a specific subset of the zone's content could abuse     these unintended additional privileges to update other contents of the zone. (CVE-2020-8624)

  - BIND servers are vulnerable if they are running an affected version and are configured to use GSS-TSIG     features. In a configuration which uses BIND's default settings the vulnerable code path is not exposed,     but a server can be rendered vulnerable by explicitly setting valid values for the tkey-gssapi-keytab or     tkey-gssapi-credentialconfiguration options. Although the default configuration is not vulnerable, GSS-     TSIG is frequently used in networks where BIND is integrated with Samba, as well as in mixed-server     environments that combine BIND servers with Active Directory domain controllers. The most likely outcome     of a successful exploitation of the vulnerability is a crash of the named process. However, remote code     execution, while unproven, is theoretically possible. Affects: BIND 9.5.0 -> 9.11.27, 9.12.0 -> 9.16.11,     and versions BIND 9.11.3-S1 -> 9.11.27-S1 and 9.16.8-S1 -> 9.16.11-S1 of BIND Supported Preview Edition.
    Also release versions 9.17.0 -> 9.17.1 of the BIND 9.17 development branch (CVE-2020-8625)

  - In BIND 9.3.0 -> 9.11.35, 9.12.0 -> 9.16.21, and versions 9.9.3-S1 -> 9.11.35-S1 and 9.16.8-S1 ->     9.16.21-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.18 of the BIND     9.17 development branch, exploitation of broken authoritative servers using a flaw in response processing     can cause degradation in BIND resolver performance. The way the lame cache is currently designed makes it     possible for its internal data structures to grow almost infinitely, which may cause significant delays in     client query processing. (CVE-2021-25219)

  - By spoofing the target resolver with responses that have a malformed ECDSA signature, an attacker can     trigger a small memory leak. It is possible to gradually erode available memory to the point where named     crashes for lack of resources. (CVE-2022-38177)

  - By spoofing the target resolver with responses that have a malformed EdDSA signature, an attacker can     trigger a small memory leak. It is possible to gradually erode available memory to the point where named     crashes for lack of resources. (CVE-2022-38178)
