The filename is not validated for traversal outside of the destination directory, and thus allows writing to locations outside of the destination. Scope: local bookworm: resolved (fixed

CVE-2021-41072 [HIGH] CVE-2021-41072: squashfs-tools - squashfs_opendir in unsquash-2.c in Squashfs-Tools 4.5 allows Directory Traversa... squashfs_opendir in unsquash-2.c in Squashfs-Tools 4.5 allows Directory Traversal, a different vulnerability than CVE-2021-40153. A squashfs filesystem that has been crafted to include a symbolic link and then contents under the same filename in a filesystem can cause unsquashfs to first create the symbolic link pointing outside the expected directory, and th

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.

Stack-based buffer overflow in the get_component function in unsquashfs.c in unsquashfs in Squashfs 4.2 and earlier allows remote attackers to execute arbitrary code via a crafted list file (aka a crafted file for the -ef option). NOTE: probably in most cases, the list file is a trusted file constructed by the program's user; however, there are some realistic
