Gdk-pixbuf: gdk-pixbuf: invalid write in jpeg icc profile parser on error recovery
CVSS Score
4.7
EPSS Score
0.0%
EPSS Percentile
0th
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
