"Michal Zalewski found a vulnerability in the util-linux package with
the chfn utility. This utility allows users to modify some information
in the /etc/passwd file, and is installed setuid root. Using a
carefully crafted attack sequence, an attacker can exploit a complex
file locking and modification race that would allow 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."
