Description
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to a flaw in the NFSv2/NFSv3 server in the nfsd subsystem. A remote attacker can use a long RPC reply related to net/sunrpc/svc.c, fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c. and cause the system to crash.
Successful exploitation of the vulnerability results in denial of service.
