Message-ID: <20111028161706.GA4193@pisco.westfalen.local> Date: Fri, 28 Oct 2011 18:17:06 +0200 From: Moritz Muehlenhoff <jmm@...ian.org> To: bugtraq@...urityfocus.com Subject: [SECURITY] [DSA 2331-1] tor security update -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- Debian Security Advisory DSA-2331-1 security@...ian.org http://www.debian.org/security/ Moritz Muehlenhoff October 28, 2011 http://www.debian.org/security/faq - -------------------------------------------------------------------------- Package : tor Vulnerability : several Problem type : remote Debian-specific: no CVE ID : CVE-2011-2768 CVE-2011-2769 It has been discovered by "frosty_un" that a design flaw in Tor, an online privacy tool, allows malicious relay servers to learn certain information that they should not be able to learn. Specifically, a relay that a user connects to directly could learn which other relays that user is connected to directly. In combination with other attacks, this issue can lead to deanonymizing the user. The Common Vulnerabilities and Exposures project has assigned CVE-2011-2768 to this issue. In addition to fixing the above mentioned issues, the updates to oldstable and stable fix a number of less critical issues (CVE-2011-2769). Please see this posting from the Tor blog for more information: https://blog.torproject.org/blog/tor-02234-released-security-patches For the oldstable distribution (lenny), this problem has been fixed in version 0.2.1.31-1~lenny+1. Due to technical limitations in the Debian archive scripts, the update cannot be released synchronously with the packages for stable. It will be released shortly. For the stable distribution (squeeze), this problem has been fixed in version 0.2.1.31-1. For the unstable and testing distributions, this problem has been fixed in version 0.2.2.34-1. For the experimental distribution, this problem have has fixed in version 0.2.3.6-alpha-1. We recommend that you upgrade your tor packages.
