This heap-based buffer overflow vulnerability occurs in the JPEG image loader due to improper validation of color component counts when processing a specially crafted JPEG image. A remote attacker can exploit this flaw without user interaction, for example, via thumbnail generation. Successful exploitation leads to application crashes and denial of service (DoS) conditions. ## Affected - `gdk-pixbuf2 (all versions)` - `gdk-pixbuf2 (all versions)` - `gdk-pixbuf2 (all versions)` - `gdk-pixbuf2 (all versions)` - `gdk-pixbuf2 (all versions)` - `gdk-pixbuf2 (all versions)` - `gdk-pixbuf2 (all versions)` - `gdk-pixbuf2 (all versions)` - `gdk-pixbuf2 (all versions)` - `gdk-pixbuf2 (all versions)` - `gdk-pixbuf2 (all versions)` - `gdk-pixbuf2 (all versions)` - `gdk-pixbuf2 (all versions)` - `gdk-pixbuf2 (all versions)` - `gdk-pixbuf2 (all versions)` - `gdk-pixbuf2 (all versions)` - `gdk-pixbuf2 (all versions)` - `gdk-pixbuf2 (all versions)` - `gdk-pixbuf2 (all versions)` - `gdk-pixbuf2 (all versions)` - `rhaiis/vllm-cuda-rhel9 (all versions)` - `rhaiis/vllm-rocm-rhel9 (all versions)` - `rhaiis/model-opt-cuda-rhel9 (all versions)` - `rhaiis/model-opt-cuda-rhel9 (all versions)` - `rhaiis/vllm-rocm-rhel9 (all versions)` - `rhaiis/vllm-cuda-rhel9 (all versions)` - `rhaiis/vllm-spyre-rhel9 (all versions)` - `glycin-loaders` - `loupe (all versions)` - `papers` - `snapshot (all versions)` - `gdk-pixbuf2` - `librsvg2` ## Remediation Refer to the linked advisories for vendor-supplied fixes and affected version ranges. ### Workarounds To reduce the risk of exploitation, avoid opening or processing untrusted JPEG image files. This operational control helps prevent the automatic triggering of the vulnerability, for example, during thumbnail generation, which could otherwise lead to application instability.
