CVE-2010-2521
Published: 07 September 2010
Multiple buffer overflows in fs/nfsd/nfs4xdr.c in the XDR implementation in the NFS server in the Linux kernel before 2.6.34-rc6 allow remote attackers to cause a denial of service (panic) or possibly execute arbitrary code via a crafted NFSv4 compound WRITE request, related to the read_buf and nfsd4_decode_compound functions.
From the Ubuntu security team
Neil Brown discovered that NFSv4 did not correctly check certain write requests. A remote attacker could send specially crafted traffic that could crash the system or possibly gain root privileges.
