An authenticated user can provide a malformed ACL to the fileserver's StoreACL RPC, causing the fileserver to crash, possibly expose uninitialized memory, and possibly store garbage data in the audit log. Malformed ACLs provided in responses to client FetchACL RPCs can cause client processes to crash and possibly expose uninitialized memory into other ACLs stored on the server.

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-4168 advisory.

    Package        : openafs     Version        : 1.8.6-5+deb11u1     CVE ID         : CVE-2024-10394 CVE-2024-10396 CVE-2024-10397     Debian Bug     :


    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 Debian 11 bullseye, these problems have been fixed in version     1.8.6-5+deb11u1.

    We recommend that you upgrade your openafs packages.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An authenticated user can provide a malformed ACL to the fileserver's StoreACL RPC, causing the fileserver     to crash, possibly expose uninitialized memory, and possibly store garbage data in the audit log.
    Malformed ACLs provided in responses to client FetchACL RPCs can cause client processes to crash and     possibly expose uninitialized memory into other ACLs stored on the server. (CVE-2024-10396)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Debian 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5842 advisory.
