Descriptions

A local user can bypass the OpenAFS PAG (Process Authentication Group)
throttling mechanism in Unix clients, allowing the user to create a PAG using
an existing id number, effectively joining the PAG and letting the user steal
the credentials in that PAG.

A local user can bypass the OpenAFS PAG (Process Authentication Group) throttling mechanism in Unix clients, allowing the user to create a PAG using an existing id number, effectively joining the PAG and letting the user steal the credentials in that PAG.

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).
