In the Linux kernel, the following vulnerability has been resolved: NFSD: Fix exposure in nfsd4_decode_bitmap() rtm@csail.mit.edu reports: > nfsd4_decode_bitmap4() will write beyond bmval[bmlen-1] if the RPC > directs it to do so. This can cause nfsd4_decode_state_protect4_a() > to write client-supplied data beyond the end of > nfsd4_exchange_id.spo_must_allow[] when called by > nfsd4_decode_exchange_id(). Rewrite the loops so nfsd4_decode_bitmap() cannot iterate beyond @bmlen. Reported by: rtm@csail.mit.edu
