medium Nessus Plugin ID 360977

Synopsis

The CentOS Linux host is missing one or more security updates.

Description

The CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS-STREAM8:CLSA-2026:1780660156 advisory.

- ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, domain=path authorization is checked before final file open/use. A symlink swap between check-time and use-time bypasses policy-denied read/write. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41. (CVE-2026-28689)

- ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, MAT decoder uses 32-bit arithmetic due to incorrect parenthesization resulting in a heap over-read. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41. (CVE-2026-28692)

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