Details
Neil McPhail discovered that snapd did not properly restrict writes to the
$HOME/bin path in the AppArmor profile for snaps using the home plug. An
attacker who could convince a user to install a malicious snap could use this
vulnerability to escape the snap sandbox. (CVE-2024-1724)
Zeyad Gouda discovered that snapd failed to properly check the file type when
extracting a snap. An attacker who could convince a user to install a malicious
snap containing non-regular files could then cause snapd to block indefinitely
while trying to read from such files and cause a denial of
service. (CVE-2024-29068)

Zeyad Gouda discovered that snapd failed to properly check the destination of
symbolic links when extracting a snap. An attacker who could convince a user to
install a malicious snap containing crafted symbolic links could then cause
snapd to write out the contents of the symbolic link destination into a
world-readable directory. This in-turn could allow a local unprivileged user to
gain access to privileged information. (CVE-2024-29069)
