TencentOS Server 2: firefox (TSSA-2024:0242)

medium Nessus Plugin ID 276335

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-2024:0242 advisory.

 Package updates are available for TencentOS Server 2 that fix the following vulnerabilities:

 CVE-2024-5688:
 The Mozilla Foundation Security Advisory describes this flaw as:

 If a garbage collection was triggered at the right time, a use-after-free could have occurred during object transplant.

 CVE-2024-5690:
 The Mozilla Foundation Security Advisory describes this flaw as:

 By monitoring the time certain operations take, an attacker could have guessed which external protocol handlers were functional on a user's system.

 CVE-2024-5691:
 The Mozilla Foundation Security Advisory describes this flaw as:

 By tricking the browser with a `X-Frame-Options` header, a sandboxed iframe could have presented a button that, if clicked by a user, would bypass restrictions to open a new window.

 CVE-2024-5693:
 The Mozilla Foundation Security Advisory describes this flaw as:

 Offscreen Canvas did not properly track cross-origin tainting, which could be used to access image data from another site in violation of same-origin policy.

 CVE-2024-5696:
 The Mozilla Foundation Security Advisory describes this flaw as:

 By manipulating the text in an `<input>` tag, an attacker could have caused corrupt memory leading to a potentially exploitable crash.

 CVE-2024-5700:
 The Mozilla Foundation Security Advisory describes this flaw as:

 Memory safety bugs present in Firefox 126, Firefox ESR 115.11, and Thunderbird 115.11. 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-2024-5702:
 The Mozilla Foundation Security Advisory describes this flaw as:

 Memory corruption in the networking stack could have led to 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.
