Vulnerability Assessment Details

MDKSA-2002:047: util-linux

Vulnerability Assessment Summary
Check for the version of the util-linux package

Detailed Explanation for this Vulnerability Assessment

The remote host is missing the patch for the advisory MDKSA-2002:047 (util-linux).


Michal Zalewski found a vulnerability in the util-linux package with the chfn
utility. This utility permits users to modify some information in the /etc/passwd
file, and is installed setuid root. Using a carefully crafted attack sequence,
a possible hacker can exploit a complex file locking and modification race that would
permit them to make changes to the /etc/passwd file. To successfully exploit this
vulnerability and obtain privilege escalation, there is a need for some
administrator interaction, and the password file must over over 4kb in size
the
attacker's entry cannot be in the last 4kb of the file.
