Debian Security Advisory DSA 1155-2 [email protected] Martin Schulze
August 24th, 2006
- --------------------------------------------------------------------------

Package : sendmail
Vulnerability : programming error
Problem type : remote
Debian-specific: no
CVE ID : CVE-2006-1173
CERT advisory : VU#146718
BugTraq ID : 18433
Debian Bug : 373801 380258

It turned out that the sendmail binary depends on libsasl2 (>= 2.1.19.dfsg1)
which is neither available in the stable nor in the the security archive.
This version is scheduled for the inclusion in the next update of the
stable release, though.

You'll have to download the referenced file for your architecture from
below and install it with dpkg -i.

As an alternative, temporarily adding the following line to
/etc/apt/sources.list will mitigate the problem as well:

deb stable-proposed-updates main

Here is the original security advisory for completeness:

Frank Sheiness discovered that a MIME conversion routine in sendmail,
a powerful, efficient, and scalable mail transport agent, could be
tricked by a specially crafted mail to perform an endless recursion.

For the stable distribution (sarge) this problem has been fixed in
version 8.13.4-3sarge2.

For the unstable distribution (sid) this problem has been fixed in
version 8.13.7-1.

We recommend that you upgrade your sendmail package.

Upgrade Instructions
- --------------------

wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given at the end of this advisory:

apt-get update
will update the internal database
apt-get upgrade
will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
