GENTOO LINUX SECURITY ANNOUNCEMENT 200303-4
- - ---------------------------------------------------------------------

          PACKAGE : sendmail
          SUMMARY : remote root exploit
             DATE : 2003-03-04 10:12 UTC
          EXPLOIT : remote
VERSIONS AFFECTED : <8.12.8
    FIXED VERSION : =>8.12.8
              CVE : CAN-2002-1337

- - ---------------------------------------------------------------------

- From advisory:

"Attackers may remotely exploit this vulnerability to gain "root" or
superuser control of any vulnerable Sendmail server. Sendmail and all
other email servers are typically exposed to the Internet in order to
send and receive Internet email. Vulnerable Sendmail servers will not be
protected by legacy security devices such as firewalls and/or packet
filters. This vulnerability is especially dangerous because the exploit
can be delivered within an email message and the attacker doesn't need
any specific knowledge of the target to launch a successful attack."

http://www.iss.net/issEn/delivery/xforce/alertdetail.jsp?oid=21950

SOLUTION

It is recommended that all Gentoo Linux users who are running
net-mail/sendmail upgrade to sendmail-8.12.8 as follows:

emerge sync
emerge -u sendmail
emerge clean
