 Mandriva Linux Security Advisory                         MDKSA-2007:240
 http://www.mandriva.com/security/
 _______________________________________________________________________
 
 Package : libnfsidmap
 Date    : December 7, 2007
 Affected: 2007.0, Corporate 4.0
 _______________________________________________________________________
 
 Problem Description:
 
 The NFSv4 ID mapper prior to 0.17 did not properly handle return values
 from the getpwnam_r() function when performing a username lookup, which
 could cause it to report a file as being owned by 'root' instead of
 'nobody' if the file exists on the server but not the client.
 
 The updated packages have been patched to correct these issues.
