TencentOS Server 3: firefox (TSSA-2023:0052)

high Nessus Plugin ID 239756

Synopsis

The remote TencentOS Server 3 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2023:0052 advisory.

Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

CVE-2023-29548:
A wrong lowering instruction in the ARM64 Ion compiler resulted in a wrong optimization result.
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-2023-29550:
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.
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-2023-29533:
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-2023-29541:
Firefox did not properly handle downloads of files ending in .desktop, which can be interpreted to run attacker-controlled commands.
CVE-2023-1945:
Unexpected data returned from the Safe Browsing API could have led to memory corruption and a potentially exploitable crash.

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.
