<h2>DTSA-11-1</h2>

<dt>Date Reported:</dt>
<dd>August 29th, 2005</dd>
<dt>Affected Package:</dt>
<dd><a href='http://packages.debian.org/src:maildrop'>maildrop</a></dd>
<dt>Vulnerability:</dt>
<dd>local privilege escalation</dd>
<dt>Problem-Scope:</dt>
<dd>local</dd>
<dt>Debian-specific:</dt>
<dd>Yes<br></dd>
<dt>CVE:</dt>
<dd>

<br></dd>
<br><dt>More information:</dt>
<dd>The lockmail binary shipped with maildrop allows for an attacker to <br>
obtain an effective gid as group "mail". Debian ships the binary with its <br>
setgid bit set, but the program does not drop privileges when run. It takes <br>
an argument that is executed, and since it does not drop privileges, an <br>
attacker can execute an arbitrary command with an effective gid of the "mail" <br>
group. <br>
</dd>
<br><dt>For the testing distribution (etch) this is fixed in version 1.5.3-1.1etch1</dt>
<dt>For the unstable distribution (sid) this is fixed in version 1.5.3-2</dt>
<br><dt>This upgrade is recommended if you use maildrop.<dt>
<br><dt>If you have the secure testing lines in your sources.list, you can update by running this command as root:</dt>
<dd>apt-get update && apt-get install maildrop</dd>
<br>
<dt>The Debian testing security team does not track security issues for then stable (sarge) and oldstable (woody) distributions. If stable is vulnerable, the Debian security team will make an announcement once a fix is ready.</dt>
<br>
