The SUSE Linux Enterprise 12 SP5 Azure kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2020-15437: Fixed a NULL pointer dereference which could have allowed local users to cause a denial of service(bsc#1179140).

CVE-2020-27777: Restrict RTAS requests from userspace (bsc#1179107).

CVE-2020-28974: Fixed a slab-out-of-bounds read in fbcon which could have been used by local attackers to read privileged information or potentially crash the kernel (bsc#1178589).

CVE-2020-28915: Fixed a buffer over-read in the fbcon code which could have been used by local attackers to read kernel memory (bsc#1178886).

CVE-2020-8694: Insufficient access control for some Intel(R) Processors may have allowed an authenticated user to potentially enable information disclosure via local access (bsc#1170415).

CVE-2020-25668: Fixed a use-after-free in con_font_op() (bsc#1178123).

CVE-2020-25704: Fixed a memory leak in perf_event_parse_addr_filter() (bsc#1178393).

CVE-2020-25669: Fixed a use-after-free read in sunkbd_reinit() (bsc#1178182).

The update package also includes non-security fixes. See advisory for details.

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

The remote Scientific Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the SLSA-2021:3327-1 advisory.

  - kernel: out-of-bounds write in xt_compat_target_from_user() in net/netfilter/x_tables.c (CVE-2021-22555)

  - kernel: race condition for removal of the HCI controller (CVE-2021-32399)

  - kernel: powerpc: RTAS calls can be used to compromise kernel integrity (CVE-2020-27777)

  - kernel: Local privilege escalation due to incorrect BPF JIT branch displacement computation     (CVE-2021-29154)

  - kernel: lack a full memory barrier upon the assignment of a new table value in net/netfilter/x_tables.c     and include/linux/netfilter/x_tables.h may lead to DoS (CVE-2021-29650)

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 5.20.2. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.20.2 advisory.

  - A flaw was found in the Routing decision classifier in the Linux kernel's Traffic Control networking     subsystem in the way it handled changing of classification filters, leading to a use-after-free condition.
    This flaw allows unprivileged local users to escalate their privileges on the system. The highest threat     from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3715)

  - Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP     transfer-encoding request header in some circumstances leading to the possibility to request smuggling     when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if     the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding;
    and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding.
    (CVE-2021-33037)

  - Vulnerability in the Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component:
    Networking). Supported versions that are affected are Java SE: 7u301, 8u291, 11.0.11, 16.0.1; Oracle     GraalVM Enterprise Edition: 20.3.2 and 21.1.0. Difficult to exploit vulnerability allows unauthenticated     attacker with network access via multiple protocols to compromise Java SE, Oracle GraalVM Enterprise     Edition. Successful attacks require human interaction from a person other than the attacker. Successful     attacks of this vulnerability can result in unauthorized read access to a subset of Java SE, Oracle     GraalVM Enterprise Edition accessible data. Note: This vulnerability applies to Java deployments,     typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load     and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for     security. 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-2021-2341)

  - Vulnerability in the Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component:
    Library). Supported versions that are affected are Java SE: 7u301, 8u291, 11.0.11, 16.0.1; Oracle GraalVM     Enterprise Edition: 20.3.2 and 21.1.0. Easily exploitable vulnerability allows unauthenticated attacker     with network access via multiple protocols to compromise Java SE, Oracle GraalVM Enterprise Edition.
    Successful attacks require human interaction from a person other than the attacker. Successful attacks of     this vulnerability can result in unauthorized update, insert or delete access to some of Java SE, Oracle     GraalVM Enterprise Edition accessible data. Note: This vulnerability applies to Java deployments,     typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load     and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for     security. 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-2021-2369)

  - Vulnerability in the Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component:
    Hotspot). Supported versions that are affected are Java SE: 8u291, 11.0.11, 16.0.1; Oracle GraalVM     Enterprise Edition: 20.3.2 and 21.1.0. Difficult to exploit vulnerability allows unauthenticated attacker     with network access via multiple protocols to compromise Java SE, Oracle GraalVM Enterprise Edition.
    Successful attacks require human interaction from a person other than the attacker. Successful attacks of     this vulnerability can result in takeover of Java SE, Oracle GraalVM Enterprise Edition. Note: This     vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start     applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the     internet) and rely on the Java sandbox for security. 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-2021-2388)

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 6.0.1.6. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.0.1.6 advisory.

  - A flaw was found in the Routing decision classifier in the Linux kernel's Traffic Control networking     subsystem in the way it handled changing of classification filters, leading to a use-after-free condition.
    This flaw allows unprivileged local users to escalate their privileges on the system. The highest threat     from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3715)

  - Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP     transfer-encoding request header in some circumstances leading to the possibility to request smuggling     when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if     the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding;
    and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding.
    (CVE-2021-33037)

  - A flaw was found in the way RTAS handled memory accesses in userspace to kernel communication. On a locked     down (usually due to Secure Boot) guest system running on top of PowerVM or KVM hypervisors (pseries     platform) a root like local user could use this flaw to further increase their privileges to that of a     running kernel. (CVE-2020-27777)

  - A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c.
    This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name     space (CVE-2021-22555)

  - BPF JIT compilers in the Linux kernel through 5.11.12 have incorrect computation of branch displacements,     allowing them to execute arbitrary code within the kernel context. This affects     arch/x86/net/bpf_jit_comp.c and arch/x86/net/bpf_jit_comp32.c. (CVE-2021-29154)
