{"schemaVersion":3,"id":"USN-6940-2","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"snapd vulnerabilities\n\nUSN-6940-1 fixed vulnerabilities in snapd. This update provides the\ncorresponding updates for Ubuntu 18.04 LTS and Ubuntu 16.04 LTS.\n\nOriginal advisory details:\n\n Neil McPhail discovered that snapd did not properly restrict writes to\n the /home/jslarraz/bin path in the AppArmor profile for snaps using the home\n plug. An attacker who could convince a user to install a malicious snap\n could use this vulnerability to escape the snap sandbox. (CVE-2024-1724)\n\n Zeyad Gouda discovered that snapd failed to properly check the file type\n when extracting a snap. An attacker who could convince a user to install\n a malicious snap containing non-regular files could then cause snapd to\n block indefinitely while trying to read from such files and cause a\n denial of service. (CVE-2024-29068)\n\n Zeyad Gouda discovered that snapd failed to properly check the\n destination of symbolic links when extracting a snap. An attacker who\n could convince a user to install a malicious snap containing crafted\n symbolic links could then cause snapd to write out the contents of the\n symbolic link destination into a world-readable directory. This in-turn\n could allow a local unprivileged user to gain access to privileged\n information.
