    Package        : sope
    CVE ID         : CVE-2025-53603
    Debian Bug     : 1108798

    Stefan Buehler discovered a flaw in sope, the set of Objective-C
    frameworks powering SOGo, which may result in denial of service via a
    specially crafted POST request.

    For the stable distribution (bookworm), this problem has been fixed in
    version 5.8.0-1+deb12u1.

    We recommend that you upgrade your sope packages.

    For the detailed security status of sope please refer to its security
    tracker page at:
    https://security-tracker.debian.org/tracker/sope

    these updates to your system and frequently asked questions can be
