CVE-2007-0816

Status: ModifiedMedium (5)—

The RPC Server service (catirpc.exe) in CA (formerly Computer Associates) BrightStor ARCserve Backup 11.5 SP2 and earlier allows remote attackers to cause a denial of service (service crash) via a crafted TADDR2UADDR that triggers a null pointer dereference in catirpc.dll, possibly related to null credentials or verifier fields.
