    Package        : openafs
    CVE ID         : CVE-2024-10394 CVE-2024-10396 CVE-2024-10397
    Debian Bug     : 1087406 1087407

    Several vulnerabilities were discovered in OpenAFS, an implementation of
    the AFS distributed filesystem, which may result in theft of credentials
    in Unix client PAGs (CVE-2024-10394), fileserver crashes and information
    leak on StoreACL/FetchACL (CVE-2024-10396) or buffer overflows in XDR
    responses resulting in denial of service and potentially code execution
    (CVE-2024-10397).

    For the stable distribution (bookworm), these problems have been fixed
    in version 1.8.9-1+deb12u1.

    We recommend that you upgrade your openafs packages.

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