TencentOS Server 3: glibc (TSSA-2024:0134)

high Nessus Plugin ID 276446

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 a vulnerability as referenced in the TSSA-2024:0134 advisory.

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

 CVE-2024-2961:
 An out-of-bounds write flaw was found in the ISO-2022-CN-EXT plugin for glibc's iconv library. When converting from UCS4 charset, adding certain escape charterers is required to indicate where the charset was changed to the library. During this process, iconv improperly checks the boundaries of internal buffers, leading to a buffer overflow, which allows writing up to 3 bytes outside the desired memory location. This issue may allow an attacker to craft a malicious characters sequence that will trigger the out-of-bounds write and perform remote code execution, presenting a high impact to the Integrity, Confidentiality, and Availability triad.

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

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

Solution

Update the affected packages.
