Debian: New gnupg packages fix signature forgery
Summary
- --------------------------------------------------------------------------Debian Security Advisory DSA 1266-1 security@debian.org http://www.debian.org/security/ Moritz Muehlenhoff March 13th, 2007 http://www.debian.org/security/faq - --------------------------------------------------------------------------Package : gnupg Vulnerability : several Problem-Type : local(remote) Debian-specific: no CVE ID : CVE-2007-1263 Debian Bug : 413922 414170 Gerardo Richarte discovered that GnuPG, a free PGP replacement, provides insufficient user feedback if an OpenPGP message contains both unsigned and signed portions. Inserting text segments into an otherwise signed message could be exploited to forge the content of signed messages. This update prevents such attacks; the old behaviour can still be activated by passing the --allow-multiple-messages option. For the stable distribution (sarge) these problems have been fixed in version 1.4.1-1.sarge7. For the upcoming stable distribution (etch) these problems have been fixed in version 1.4.6-2. For the unstable distribution (sid) these problems have been fixed in version 1.4.6-2. We recommend that you upgrade your gnupg packages. Upgrade Instructions - --------------------wget url will fetch the file for you dpkg -i file.deb will install the referenced file.
