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)

  - 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)

  - 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)

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)
