Summary

gdk-pixbuf2 security update

Details

gdk is written in C but has been designed from the ground up to support a wide range of languages. It provide a complete set of widgets,and suitable for projects ranging from small one-off tools to complete application suites.

Security Fix(es):

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.(CVE-2026-81893)

Severity

4.7 (Medium)
