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.
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.
OpenAFS before 1.6.24 and 1.8.x before 1.8.5 is prone to denial of service from unserialized data access because remote attackers can make a series of VOTE_Debug RPC calls to crash a database server within the SVOTE_Debug RPC handler.
OpenAFS before 1.6.24 and 1.8.x before 1.8.5 is prone to an information disclosure vulnerability because uninitialized scalars are sent over the network to a peer.
OpenAFS before 1.6.24 and 1.8.x before 1.8.5 is prone to information leakage upon certain error conditions because uninitialized RPC output variables are sent over the network to a peer.
