CVE-2021-40153 (GCVE-0-2021-40153)

Vulnerability from cvelistv5 – Published: 2021-08-27 00:00 – Updated: 2024-08-04 02:27

Summary

squashfs_opendir in unsquash-1.c in Squashfs-Tools 4.5 stores the filename in the directory entry; this is then used by unsquashfs to create the new file during the unsquash. The filename is not validated for traversal outside of the destination directory, and thus allows writing to locations outside of the destination.

Severity ?

No CVSS data available.

CVE-2021-41072 (GCVE-0-2021-41072)

Vulnerability from cvelistv5 – Published: 2021-09-14 00:00 – Updated: 2024-08-04 02:59

Summary

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 then the subsequent write operation will cause the unsquashfs process to write through the symbolic link elsewhere in the filesystem.

Severity ?

No CVSS data available.
