Synopsis
The remote TencentOS Server 2 host is missing one or more security updates.
Description
The version of Tencent Linux installed on the remote TencentOS Server 2 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2023:0059 advisory.
Package updates are available for TencentOS Server 2 that fix the following vulnerabilities:
CVE-2023-0547:
OCSP revocation status of recipient certificates was not checked when sending S/Mime encrypted email, and revoked certificates would be accepted. Thunderbird versions from 68 to 102.9.1 were affected by this bug.
CVE-2023-1945:
Unexpected data returned from the Safe Browsing API could have led to memory corruption and a potentially exploitable crash.
CVE-2023-1999:
A double-free in libwebp could have led to memory corruption and a potentially exploitable crash.
CVE-2023-28427:
matrix-js-sdk is a Matrix messaging protocol Client-Server SDK for JavaScript. In versions prior to 24.0.0 events sent with special strings in key places can temporarily disrupt or impede the matrix-js-sdk from functioning properly, potentially impacting the consumer's ability to process data safely. Note that the matrix-js-sdk can appear to be operating normally but be excluding or corrupting runtime data presented to the consumer. This vulnerability is distinct from GHSA-rfv9-x7hh-xc32 which covers a similar issue. The issue has been patched in matrix-js-sdk 24.0.0 and users are advised to upgrade. There are no known workarounds for this vulnerability.
CVE-2023-29479:
Certain malformed OpenPGP messages could trigger incorrect parsing of PKESK/SKESK packets due to a bug in the Ribose RNP library used by Thunderbird up to version 102.9.1, which would cause the Thunderbird user interface to hang. The issue was discovered using Google's oss-fuzz.
CVE-2023-29533:
A website could have obscured the fullscreen notification by using a combination of window.open, fullscreen requests, window.name assignments, and setInterval calls. This could have led to user confusion and possible spoofing attacks.
CVE-2023-29535:
FolLowing a Garbage Collector compaction, weak maps may have been accessed before they were correctly traced. This resulted in memory corruption and a potentially exploitable crash.
CVE-2023-29536:
An attacker could cause the memory manager to incorrectly free a pointer that addresses attacker- controlled memory, resulting in an assertion, memory corruption, or a potentially exploitable crash.
CVE-2023-29539:
When handling the filename directive in the Content-Disposition header, the filename would be truncated if the filename contained a NULL character. This could have led to reflected file download attacks potentially tricking users to install malware.
CVE-2023-29541:
Firefox did not properly handle downloads of files ending in .desktop, which can be interpreted to run attacker-controlled commands.
CVE-2023-29548:
A wrong Lowering instruction in the ARM64 Ion compiler resulted in a wrong optimization result.
CVE-2023-29550:
Mozilla developers Andrew Osmond, Sebastian Hengst, Andrew McCreight, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 111 and Firefox ESR 102.9. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code.
Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Update the affected packages.
