TencentOS Server 3: libvpx (TSSA-2023:0243)

high Nessus Plugin ID 240016

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-2023:0243 advisory.

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

 CVE-2023-5217:
 Heap buffer overflow in vp8 encoding in libvpx in Google Chrome prior to 117.0.5938.132 and libvpx 1.13.1 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)

 CVE-2023-44488:
 VP9 in libvpx before 1.13.1 mishandles widths, leading to a crash related to encoding.

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.
