------------------------------------------------------------------------- Debian LTS Advisory DLA-4796-1 [email protected] https://www.debian.org/lts/security/ Andreans Henriksson September 25, 2026 https://wiki.debian.org/LTS
-------------------------------------------------------------------------

Package : evolution-data-server Version : 3.46.4-2+deb12u1 CVE ID : CVE-2026-2604 Debian Bug : 1128332

An issue has been found in evolution-data-server, an evolution database backend server. A Flatpak application with D-Bus access to the addressbook service can delete arbitrary files on the host, potentially including Flatpak override files. This fix canonicalizes the file path before performing a prefix comparison, ensuring that ../ sequences are resolved.

For Debian 12 bookworm, this problem has been fixed in version 3.46.4-2+deb12u1.

We recommend that you upgrade your evolution-data-server packages.
