SUSE-SA:2005:064: pwdutils, shadow
High Nessus Plugin ID 20209
SynopsisThe remote host is missing a vendor-supplied security patch
DescriptionThe remote host is missing the patch for the advisory SUSE-SA:2005:064 (pwdutils, shadow).
Thomas Gerisch found that the setuid 'chfn' program contained in the pwdutils suite insufficiently checks it's arguments when changing the GECOS field. This bug leads to a trivially exploitable local privilege escalation that allows users to gain root access.
We like to thank Thomas Gerisch for pointing out the problem.
