Description

jaguar@felinemenace.org discovered a format string vulnerability in log2mail, whereby a user able to log a specially crafted message to a logfile monitored by log2mail (for example, via syslog) could cause arbitrary code to be executed with the privileges of the log2mail process. By default, this process runs as user 'log2mail', which is a member of group 'adm' (which has access to read system logfiles).

CAN-2004-0450: log2mail format string vulnerability via syslog(3) in printlog()
