Description Mark J. Cox (Product Security) 2003-06-23 03:32:57 EDT
Janusz Niewiadomski found a buffer overflow bug in nfs-utils version 1.0.3
and earlier. This bug could be exploited by an attacker to cause a remote
Denial of Service (crash). It is not believed that this bug could lead to
remote arbitrary code execution. 

example:

mount somehost:`perl -e 'for($i=0;$i<1000;$i++){print "A";}'` /mnt

This is RHSA-2003:207, erratum in process.
