github.com/containers/podman: Podman: Host filesystem modification via malicious container image WORKDIR symlink

A flaw was found in Podman. A remote attacker can exploit this vulnerability by running a malicious container image where the WORKDIR working directory path contains a symbolic link symlink. This can lead to the creation of a directory or modification of ownership on the host filesystem,...

runc: Malicious image with /dev symlink can trigger limited host filesystem integrity violations

Impact When setting up the container rootfs, setupPtmx and setupDevSymlinks call os.Remove and os.Symlink with a filepath.Join string which allow an image with /dev as a symlink to trick runc into deleting files called ptmx on the host or creating a hardcoded set of symlinks with specific names a...

GHSA-Q6R4-3WMG-FWCQ Podman: WORKDIR symlink traversal vulnerability

Summary Running a malicous container image where the WORKDIR path contains a symlink can create a directory or modify ownership on the host filesystem. Modified ownership is less likely to happen as that requires help from an untrusted/malicious process that mutates the host filesystem tree durin...

CVE-2026-2604 Evolution-data-server: evolution data server: arbitrary file deletion via inconsistent uri handling

A flaw was found in evolution-data-server. Inconsistent comparison logic in the addressbook file backend allows a Flatpak application with D-Bus access to craft a malicious URI containing directory traversal sequences. This URI is stored without proper validation during contact creation or...
