===================================================================== CERT-Renater Note d'Information No. 2006/VULN469 _____________________________________________________________________ DATE : 28/08/2006 HARDWARE PLATFORM(S) : / OPERATING SYSTEM(S) : Debian running Sendmail. ====================================================================== - - -------------------------------------------------------------------------- Debian Security Advisory DSA 1155-2 security@debian.org http://www.debian.org/security/ Martin Schulze August 24th, 2006 http://www.debian.org/security/faq - - -------------------------------------------------------------------------- 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 http://ftp.debian.de/debian 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.
