The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-142368 advisory.

    GNU Emacs before 31.0.91 contains an integer overflow in the PBM/PPM/PGM image loader that allows an     attacker to leak heap memory contents by supplying a crafted image with large dimensions and an elevated     max color index. The image loader multiplies image dimensions and channel count using signed integer     arithmetic; for sufficiently large values, the result wraps to a negative number, bypassing the bounds     check and causing the pixel reader to access heap memory past the end of the allocated buffer. The over-     read contents are interpreted as pixel color values and rendered on screen.

    A flaw was found in Emacs TRAMP. A local attacker could exploit this vulnerability by processing     maliciously crafted filenames. This occurs because TRAMP concatenates login arguments without proper     sanitization, which are then passed to a local shell. Successful exploitation could lead to arbitrary code     execution. (CVE-2026-79992)

(CVE-2026-79992)

    GNU Emacs 28.1 through 31.1 allows arbitrary code execution upon opening a file, because an untrusted     value of read-symbol-shorthands affects the intern and unintern functions. This affects the default     configuration; no particular user settings are required to trigger it. (CVE-2026-96269)
