An update of the apache package has been released.

According to the versions of the tomcat packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - 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)

  - 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)

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 version of AOS installed on the remote host is prior to 5.17.1.3. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.17.1.3 advisory.

  - An issue was discovered in the Linux kernel before 4.14.11. A double free may be caused by the function     allocate_trace_buffer in the file kernel/trace/trace.c. (CVE-2017-18595)

  - An issue was discovered in dbus >= 1.3.0 before 1.12.18. The DBusServer in libdbus, as used in dbus-     daemon, leaks file descriptors when a message exceeds the per-message file descriptor limit. A local     attacker with access to the D-Bus system bus or another system service's private AF_UNIX socket could use     this to make the system service reach its file descriptor limit, denying service to subsequent D-Bus     clients. (CVE-2020-12049)

  - In the Linux kernel 5.4.0-rc2, there is a use-after-free (read) in the __blk_add_trace function in     kernel/trace/blktrace.c (which is used to fill out a blk_io_trace structure and place it in a per-cpu sub-     buffer). (CVE-2019-19768)

  - A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7.
    This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into     the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO     restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate     that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer     dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network     user to crash the system kernel, resulting in a denial of service. (CVE-2020-10711)

  - 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)

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

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-017616 advisory.

    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.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Two vulnerabilities were discovered in the Tomcat servlet and JSP engine, which could result in information disclosure or denial of service.

This update for tomcat fixes the following issues :

CVE-2021-25122: Apache Tomcat h2c request mix-up (bsc#1182912) CVE-2021-25329: Complete fix for CVE-2020-9484 (bsc#1182909)

This update was imported from the SUSE:SLE-15-SP2:Update update project.

The version of Tomcat installed on the remote host is prior to 7.0.108. It is, therefore, affected by a vulnerability as referenced in the fixed_in_apache_tomcat_7.0.108_security-7 advisory.

  - 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.

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.

  - encoding.c in GNU Screen through 4.8.0 allows remote attackers to cause a denial of service (invalid write     access and application crash) or possibly have unspecified other impact via a crafted UTF-8 character     sequence. (CVE-2021-26937)

  - Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow     unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.
    (CVE-2017-5715)

  - Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized     disclosure of information to an attacker with local user access via a side-channel analysis.
    (CVE-2017-5753)

  - Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow     unauthorized disclosure of information to an attacker with local user access via a side-channel analysis     of the data cache. (CVE-2017-5754)

  - 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;
    Java SE Embedded: 8u281; Oracle GraalVM Enterprise Edition: 19.3.5, 20.3.1.2 and 21.0.0.2. Difficult to     exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to     compromise Java SE, Java SE Embedded, 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 creation, deletion or modification access to critical data or all Java SE, Java SE Embedded,     Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability applies to Java deployments     that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox     for security. (CVE-2021-2163)
