TencentOS Server 3: glibc (TSSA-2024:0233)

high Nessus Plugin ID 239029

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-2024:0233 advisory.

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

 CVE-2024-33599:
 A stack-based buffer overflow flaw was found in the glibc netgroup cache. In certain conditions, its possible to trigger a stack-based buffer overflow condition that can lead to a denial of service and potentially other malicious actions that impact confidentiality and integrity.

 CVE-2024-33600:
 A flaw was found in the glibc netgroup cache. After a failed cache insertion, addgetnetgrentX tries to send the non-existing response after the not-found header. This can lead to a null pointer dereference that causes a crash or exit.

 CVE-2024-33601:
 A flaw was found in the glibc netgroup cache. The netgroup cache uses xmalloc/xrealloc and may terminate the process due to a memory allocation failure.

 CVE-2024-33602:
 A flaw was found in the glibc netgroup cache. The buffer-resizing code in addgetnetgrentX assumes that all string pointers point into the supplied buffer. This can potentially lead to memory corruption and cause a 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.
