CVE-2022-3560: A flaw was found in pesign. The pesign package provides a systemd service used to start the pesign daemon. This service unit runs a script to set ACLs for /etc/pki/pesign and /run/pesign directories to grant access privileges to users in the 'pesign' group. However, the script doesn't check for symbolic links. This could allow an attacker to gain access to privileged files and directories via a path traversal attack. RedHat managed to make the CVE itself completely opaque, but there's more information on oss-security: https://www.openwall.com/lists/oss-security/2023/01/31/6 https://www.openwall.com/lists/oss-security/2023/02/01/2 But even these don't say that the fixed version is 116. It's not in the release notes either: https://github.com/rhboot/pesign/releases/tag/116 But it is noted in the relase commit: https://github.com/rhboot/pesign/commit/c8d7c76f1848d324ee3b72ca602d01b988e6238e The fix itself is https://github.com/rhboot/pesign/commit/d8a8c259994d0278c59b30b41758a8dd0abff998
