CVE-2026-109273 ImageMagick CVE debrief

ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains an information disclosure vulnerability in the PostScript decoder. The vulnerability allocates a buffer one byte longer than the data it decoded, allowing attackers to supply a crafted PostScript file to expose a single uninitialized byte of memory contents. This issue affects ImageMagick installations and users who process PostScript files. Defenders should assess exposure and prioritize patching to prevent potential information disclosure.
