En bref
- CVE-2024-29069 est une vulnérabilité ÉLEVÉE (CVSS 7.3) touchant github.com/snapcore/snapd, snapd (canonical).
- Probabilité d'exploitation dans les 30 prochains jours (EPSS) : 0.23%, plus élevée que 13.6% des vulnérabilités.
- Correctif : mettre à jour vers 2.62 ou plus récent.
Description
In snapd versions prior to 2.62, snapd failed to properly check the destination of symbolic links when extracting a snap. The snap format is a squashfs file-system image and so can contain symbolic links and other file types. Various file entries within the snap squashfs image (such as icons and desktop files etc) are directly read by snapd when it is extracted. An attacker who could convince a user to install a malicious snap which contained symbolic links at these paths could then cause snapd to write out the contents of the symbolic link destination into a world-readable directory. This in-turn could allow an unprivileged user to gain access to privileged information.
