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. 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.
