FreeBSD Security Advisory - FreeBSD-SA-26:08.rpcsec_gss

FreeBSD Security Advisory - Each RPCSECGSS data packet is validated by a routine which checks a signature in the packet. This routine copies a portion of the packet into a stack buffer, but fails to ensure that the buffer is sufficiently large, and a malicious client can trigger a stack overflow...
