TencentOS Server 2: ImageMagick (TSSA-2025:1011)

critical Nessus Plugin ID 310959

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 a vulnerability as referenced in the TSSA-2025:1011 advisory.

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

CVE-2025-57803:
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-28 and 7.1.2-2 for ImageMagick's 32-bit build, a 32-bit integer overflow in the BMP encoders scanline-stride computation collapses bytes_per_line (stride) to a tiny value while the per- row writer still emits 3 width bytes for 24-bpp images. The row base pointer advances using the (overflowed) stride, so the first row immediately writes past its slot and into adjacent heap memory with attacker-controlled bytes. This is a classic, powerful primitive for heap corruption in common auto- convert pipelines. This issue has been patched in versions 6.9.13-28 and 7.1.2-2.

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.
