Name of the Vulnerable Software and Affected Versions GdkPixbuf versions prior to 2.42.8

Description The issue is related to a heap-based buffer overflow in the composite frame() function of the GdkPixbuf library when handling GIF files. This overflow can be exploited to execute arbitrary code, particularly on 32-bit systems.
