Description
Qualys discovered a race condition (CVE-2022-3328) in snap-confine, a SUID-root program installed by default on Ubuntu. In this advisory,they tell the story of this vulnerability (which was introduced in February 2022 by the patch for CVE-2021-44731) and detail how they exploited it in Ubuntu Server (a local privilege escalation, from any user to root) by combining it with two vulnerabilities in multipathd (an authorization bypass and a symlink attack, CVE-2022-41974 and CVE-2022-41973).
