FreeBSD : virtualenv -- CWE-59: Improper Link Resolution Before File Access ('Link Following') (fd3855b8-efbc-11f0-9e3f-b0416f0c4c67)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the fd3855b8-efbc-11f0-9e3f-b0416f0c4c67 advisory. https://github.com/pypa/virtualenv/security/advisories/GHSA-597g-3phw-6986 reports: virtualenv is a too...

runc: container escape with malicious config due to /dev/console mount and related races

A flaw was found in runc. CVE-2025-52565 is very similar in concept and application toCVE-2025-31133, except that it exploits a flaw in /dev/console bind-mounts. When creating the /dev/console bind-mount to /dev/pts/$n, if an attacker replaces /dev/pts/$n with a symlink then runc will bind-mount...
