    Package        : libxslt
    CVE ID         : CVE-2024-55549 CVE-2025-24855
    Debian Bug     : 1100565 1100566

    Ivan Fratric discovered two use-after-free vulnerabilities in libxslt,
    an XSLT processing runtime library, which may result in the execution of
    arbitrary code if a specially crafted files are processed.

    For the stable distribution (bookworm), these problems have been fixed in
    version 1.1.35-1+deb12u1.

    We recommend that you upgrade your libxslt packages.

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