      Date: December 14, 2005
      Bugs: #109381
        ID: 200512-05

Synopsis
=======
The sendmail program in Xmail is vulnerable to a buffer overflow,
potentially resulting in local privilege escalation.

Background
=========
Xmail is an Internet and intranet mail server.

Affected packages
================
    -------------------------------------------------------------------
     Package         /  Vulnerable  /                       Unaffected
    -------------------------------------------------------------------
  1  mail-mta/xmail       < 1.22                               >= 1.22

Description
==========
iDEFENSE reported that the AddressFromAtPtr function in the sendmail
program fails to check bounds on arguments passed from other functions,
and as a result an exploitable stack overflow condition occurs when
specifying the "-t" command line option.

Impact
=====
A local attacker can make a malicious call to sendmail, potentially
resulting in code execution with elevated privileges.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All Xmail users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=mail-mta/xmail-1.22"
