Descriptions

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.

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.

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).
