Description

 SUSE Linux contains a flaw that may allow a malicious user to gain access to unauthorized privileges. The problem is that the setuid 'chfn' binary in the 'pwdutils' suite does not properly check arguments when changing the 'GECOS' field, which may allow a malicious user to gain access to root privileges resulting in a loss of integrity.
