CVE-2024-29069

Privileged file disclosure via unchecked snap symlinks

Published Jul 25, 2024 · Updated Aug 2, 2024

Information disclosure in Canonical snapd before 2.62 allows attackers to expose privileged file contents through crafted snap symlinks. The snap container validator reads metadata paths without rejecting links that resolve outside the SquashFS image, then copies target contents into a world-readable directory. Exploitation requires user installation of the crafted snap; afterward, a local unprivileged user can read the exposed privileged data.
