========================================================================== Ubuntu Security Notice USN-5753-1 December 01, 2022
snapd vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.10 - Ubuntu 22.04 LTS - Ubuntu 20.04 LTS - Ubuntu 18.04 LTS - Ubuntu 16.04 ESM
Summary:
snapd could be made to run programs as an administrator.
Software Description: - snapd: Daemon and tooling that enable snap packages
Details:
The Qualys Research Team discovered that a race condition existed in the snapd snap-confine binary when preparing the private /tmp mount for a snap. A local attacker could possibly use this issue to escalate privileges and execute arbitrary code.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 22.10: snapd 2.57.5+22.10ubuntu0.1
Ubuntu 22.04 LTS: snapd 2.57.5+22.04ubuntu0.1

Ubuntu 18.04 LTS: snapd 2.57.5+18.04ubuntu0.1
Ubuntu 16.04 ESM: snapd 2.54.3+16.04.0ubuntu0.1~esm5
