Title:	Ubuntu: Security Advisory (USN-6940-2)
Summary:	The remote host is missing an update for the 'snapd' package(s) announced via the USN-6940-2 advisory.
Description:	Summary: The remote host is missing an update for the 'snapd' package(s) announced via the USN-6940-2 advisory. Vulnerability Insight: USN-6940-1 fixed vulnerabilities in snapd. This update provides the corresponding updates for Ubuntu 18.04 LTS and Ubuntu 16.04 LTS. Original advisory details: Neil McPhail discovered that snapd did not properly restrict writes to the /home/jslarraz/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) Affected Software/OS: 'snapd' package(s) on Ubuntu 16.04, Ubuntu 18.04. Solution: Please install the updated package(s). CVSS Score: 6.8 CVSS Vector: AV:L/AC:L/Au:S/C:C/I:C/A:C
