Description:
A vulnerability has been reported in nfs-utils, which potentially can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error (off-by-one) in the "xlog()" function when adding missing trailing newlines to a logged string. This can be exploited by sending a specially crafted RPC request to the rpc.mountd service, which may cause it to crash or potentially allow execution of arbitrary code.

The vulnerability has been reported to affect versions 1.0.3 and prior.
