<title>Xmail: Privilege escalation through sendmail</title>
The sendmail program in Xmail is vulnerable to a buffer overflow,
potentially resulting in local privilege escalation.
<product type="ebuild">xmail</product>
<announced>December 14, 2005</announced>
<revised>December 14, 2005: 01</revised>
<package name="mail-mta/xmail" auto="yes" arch="*">
<unaffected range="ge">1.22</unaffected>
<vulnerable range="lt">1.22</vulnerable>
Xmail is an Internet and intranet mail server.
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 type="high">
A local attacker can make a malicious call to sendmail,
potentially resulting in code execution with elevated privileges.
There is no known workaround at this time.
All Xmail users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=mail-mta/xmail-1.22&quot;</code>
