A flaw was found in the file-pix (ESM) plugin in GIMP. When processing a specially crafted PIX image file, the plugin allocates a Variable-Length Array (VLA) on the stack without proper bounds checking, causing an unbounded stack allocation followed by a 21-byte stack over-read. This can result in a denial of service due to stack exhaustion and a limited information disclosure of stack memory contents into an intermediate file.

The remote Debian 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6509 advisory.

    Several vulnerabilities were discovered in GIMP, the GNU Image     Manipulation Program, which could result in denial of service     or potentially the execution of arbitrary code if malformed     PSD, light effects filter, ICO, PIX or PCX files are opened.

    For the stable distribution (trixie), these problems have been fixed in     version 3.0.4-3+deb13u11.

    We recommend that you upgrade your gimp packages.
