-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- Debian Security Advisory DSA 1394-1 security@xxxxxxxxxx http://www.debian.org/security/ Thijs Kinkhorst October 23rd, 2007 http://www.debian.org/security/faq - -------------------------------------------------------------------------- Package : reprepro Vulnerability : authentication bypass Problem-Type : remote Debian-specific: yes CVE ID : CVE-2007-4739 Debian Bug : 440535 It was discovered that reprepro, a tool to create a repository of Debian packages, when updating from a remote site only checks for the validity of known signatures, and thus does not reject packages with only unknown signatures. This allows an attacker to bypass this authentication mechanism. The oldstable distribution (sarge) is not affected by this problem. For the stable distribution (etch) this problem has been fixed in version 1.3.1+1-1. For the unstable distribution (sid) this problem has been fixed in version 2.2.4-1. We recommend that you upgrade your reprepro 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 below: 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.
