This signature detects attempts to exploit a known vulnerability in rpc.mountd that ships with the nfs-utils package for Red Hat Linux versions 6.x. Because the logging mechanism for rpc.mountd contains an off-by-one vulnerability, attackers can send a maliciously crafted request to rpc.mountd to execute arbitrary code or cause a denial of service (DoS).
A remote exploitable buffer overrun vulnerability has been reported in the xlog component of nfs-utils. It is possible to exploit this issue via mountd. It has been reported that exploitation of this issue will most likely result in a denial of service. There is a possibility that this issue could be exploited to run arbitrary code in the context of mountd, which runs as root.
