CVE-2012-4025

Estado: ModificadaMedia (6.8)—

Integer overflow in the queue_init function in unsquashfs.c in unsquashfs in Squashfs 4.2 and earlier allows remote attackers to execute arbitrary code via a crafted block_log field in the superblock of a .sqsh file, leading to a heap-based buffer overflow.
