FreeBSD Security Advisory FreeBSD-SA-00:44 - The xlockmore port, versions 4.17 and below, installs the setuid root binary xlock, which contains a vulnerability due to incorrect use of the syslog() function. The xlock program correctly drops root privileges prior to the point of vulnerability, however it may retain in memory part of the hashed password database for the user accounts on the system. Attackers who can retrieve hashed password information from the memory space of the process can mount attacks against the user account passwords and possibly gain access to accounts on the system if successful.
