TencentOS Server 4: libtiff (TSSA-2025:0748)

high Nessus Plugin ID 270640

Synopsis

The remote TencentOS Server 4 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2025:0748 advisory.

Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

CVE-2025-9900:
A flaw was found in Libtiff. This vulnerability is a write-what-where condition, triggered when the library processes a specially crafted TIFF image file.

By providing an abnormally large image height value in the file's metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user.

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.
