CVE-2007-4135 Information

Description

The NFSv4 ID mapper (nfsidmap) before 0.17 does not properly handle return values from the getpwnam_r function when performing a username lookup which can cause it to report a file as being owned by \root\ instead of \nobody\ if the file exists on the server but not on the client.
