A updated masqmail package is now available for Debian GNU/Linux
A set of buffer overflows have been discovered in masqmail, a mail transport agent for hosts without permanent internet connection. In addition to this privileges were dropped only after reading a user supplied configuration file. Together this could be exploited to gain unauthorized root access to the machine on which masqmail is installed.Read more
These problems have been fixed in version 0.1.16-2.1 for the current stable distribution (woody) and in version 0.2.15-1 for the unstable distribution (sid). The old stable distribution (potato) is not affected since it doesn't contain a masqmail package.
