Arbitrary Code Execution
Overview Affected versions of this package are vulnerable to Arbitrary Code Execution due to improper validation of the snap-confine binary location. A local attacker could possibly use this issue to execute other arbitrary binaries and escalate privileges. Remediation Upgrade...
New Linux Privilege Escalation Flaw Uncovered in Snap Package Manager
Multiple security vulnerabilities have been disclosed in Canonical's Snap software packaging and deployment system, the most critical of which can be exploited to escalate privilege to gain root privileges. Snaps are self-contained application packages that are designed to work on operating syste...

CVE-2021-44730
snapd 2.54.2 did not properly validate the location of the snap-confine binary. A local attacker who can hardlink this binary to another location to cause snap-confine to execute other arbitrary binaries and hence gain privilege escalation. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and...
CVE-2021-44731
A race condition existed in the snapd 2.54.2 snap-confine binary when preparing a private mount namespace for a snap. This could allow a local attacker to gain root privileges by bind-mounting their own contents inside the snap's private mount namespace and causing snap-confine to execute arbitra...
CVE-2021-4120
snapd 2.54.2 fails to perform sufficient validation of snap content interface and layout paths, resulting in the ability for snaps to inject arbitrary AppArmor policy rules via malformed content interface and layout declarations and hence escape strict snap confinement. Fixed in snapd versions...
