## Overview

A flaw was found in gdk-pixbuf. When loading a specially crafted JPEG image containing chunked ICC profile markers, an error during ICC profile parsing can leave stale size metadata after the profile buffer is freed. A subsequent allocation in the same decode can cause an out-of-bounds write, potentially crashing the application. To exploit this flaw, an application using gdk-pixbuf must process the malicious JPEG image.

Affected version >= 2.26.4

## Affected

- `gdk-pixbuf2 (all versions)`
- `glycin-loaders`
- `loupe`
- `snapshot`
- `gdk-pixbuf2`
- `gdk-pixbuf2 (all versions)`
- `gdk-pixbuf2 (all versions)`
- `gdk-pixbuf2 (all versions)`

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.

### Workarounds

Avoid opening or automatically indexing untrusted JPEG images with applications linked against a vulnerable gdk-pixbuf version until an updated package is installed.
