NFS: Mount Request Denial of Service
This signature detects attempts to exploit a known denial of service vulnerability in the FreeBSD NFS daemon. A remote unauthenticated attacker can send maliciously crafted request packets to the target NFS daemon, which can result in a kernel panic condition and force a reboot.
Extended Description
FreeBSD is susceptible to a remote denial-of-service vulnerability. This issue is due to a flaw in affected versions of the kernel that potentially results in a crash when handling malformed RPC messages through TCP. This issue allows remote attackers to cause affected systems to crash, denying further network service to legitimate users.
