{"id":"USN-6940-2","summary":"snapd vulnerabilities","details":"USN-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. (CVE-2024-29069)\n","modified":"2026-02-10T04:44:43Z","published":"2025-01-13T10:16:20Z","related":["UBUNTU-CVE-2024-1724","UBUNTU-CVE-2024-29068","UBUNTU-CVE-2024-29069"],"upstream":["CVE-2024-1724","CVE-2024-29068","CVE-2024-29069","UBUNTU-CVE-2024-1724","UBUNTU-CVE-2024-29068","UBUNTU-CVE-2024-29069"],"references":[{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6940-2"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-1724"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-29068"},{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-29069"}],"affected":[{"package":{"name":"snapd","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/snapd@2.61.4ubuntu0.16.04.1+esm1?arch=source&distro=esm-infra/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.61.4ubuntu0.16.04.1+esm1"}]}],"versions":["1.9","1.9.1.1","1.9.2","2.0","2.0.1","2.0.2","2.0.3","2.0.5","2.0.8","2.0.9","2.0.10","2.11+0.16.04","2.12+0.16.04","2.13","2.14.2~16.04","2.15.2ubuntu1","2.16ubuntu3","2.17.1ubuntu1","2.20.1ubuntu1","2.21","2.22.2","2.22.3","2.22.6","2.23.1","2.24.1","2.25","2.26.10","2.27.5","2.28.5","2.29.4.2","2.32.3.2","2.32.9","2.33.1ubuntu2","2.34.2","2.34.2ubuntu0.1","2.37.4","2.37.4ubuntu0.1","2.38","2.39.2","2.39.2ubuntu0.2","2.40","2.42.1","2.45.1","2.45.1ubuntu0.2","2.46.1","2.47.1","2.48","2.48.3","2.54.3+16.04~esm2","2.54.3+16.04.0ubuntu0.1~esm3","2.54.3+16.04.0ubuntu0.1~esm4","2.54.3+16.04.0ubuntu0.1~esm5","2.54.3+16.04.0ubuntu0.1~esm6"],"ecosystem_specific":{"availability":"Available
