Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In GNOME GdkPixbuf (aka gdk-pixbuf) through 2.42.10, the ANI (Windows animated cursor) decoder encounters heap memory corruption (in ani_load_chunk in io-ani.c) when parsing chunks in a crafted .ani file. A crafted file could allow an attacker to overwrite heap metadata, leading to a denial of service or code execution attack. This occurs in gdk_pixbuf_set_option() in gdk-pixbuf.c.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

How this class of weakness works · CWE-787

The program writes past the bounds of a buffer, overwriting adjacent memory an attacker can turn to their advantage. Crafted input can overwrite control data and redirect execution. Remediation is validating every index and length before a write, plus modern memory-safety mitigations.

Recommended fix High confidence

GdkPixbuf 2.42.11 or later

  1. 1. Identify all systems, applications, or distributions using GdkPixbuf version 2.42.10 or earlier.
  2. 2. Check the current installed version of GdkPixbuf using package manager commands (e.g., `pkg-config --modversion gdk-pixbuf-2.0` or `dpkg -l libgdk-pixbuf2.0-0` on Debian-based systems).
  3. 3. Upgrade GdkPixbuf to version 2.42.11 or later using your system's package manager (e.g., `apt-get update && apt-get install libgdk-pixbuf2.0-0` or equivalent).
  4. 4. Rebuild any applications that statically link against GdkPixbuf to ensure they use the updated library.
  5. 5. Verify the upgrade was successful by checking the new version and testing applications that depend on GdkPixbuf.
