| CVE-2015-4645 | Med | 0.29 | 5.5 | 0.03 | Mar 17, 2017 | Integer overflow in the read_fragment_table_4 function in unsquash-4.c in Squashfs and sasquatch allows remote attackers to cause a denial of service (application crash) via a crafted input, which triggers a stack-based buffer overflow. | ||
| CVE-2025-40200 | 0.00 | — | 0.00 | Nov 12, 2025 | In the Linux kernel, the following vulnerability has been resolved: Squashfs: reject negative file sizes in squashfs_read_inode() Syskaller reports a "WARNING in ovl_copy_up_file" in overlayfs. This warning is ultimately caused because the underlying Squashfs file system… | |||
