snap-confine must_mkdir_and_open_with_perms() Race Condition

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).

CVE-2021-3995: Invalid Bug ID

A logic error was found in the libmount library of util-linux in the function that allows an unprivileged user to unmount a FUSE filesystem. This flaw allows an unprivileged local attacker to unmount FUSE filesystems that belong to certain other users who have a UID that is a prefix of the UID of the attacker in its string form. An attacker may use this flaw to cause a denial of service to applications that use the affected filesystems.

CVE-2021-3996: libmount: remove support for deleted mount table entries · util-linux/util-linux@166e873

A logic error was found in the libmount library of util-linux in the function that allows an unprivileged user to unmount a FUSE filesystem. This flaw allows a local user on a vulnerable system to unmount other users' filesystems that are either world-writable themselves (like /tmp) or mounted in a world-writable directory. An attacker may use this flaw to cause a denial of service to applications that use the affected filesystems.

CVE-2022-0563: [ANNOUNCE] util-linux v2.37.4

A flaw was found in the util-linux chfn and chsh utilities when compiled with Readline support. The Readline library uses an "INPUTRC" environment variable to get a path to the library config file. When the library cannot parse the specified file, it prints an error message containing data from the file. This flaw allows an unprivileged user to read root-owned files, potentially leading to privilege escalation. This flaw affects util-linux versions prior to 2.37.4.
