Apparently, I wasn't able to assign enough time to this issue and produced insufficiently tested updates. I'll do my best not to repeat this. This update fixes the second problem from the original advisory: When run-mailcap is executed on a file with a potentially problematic filename, a temporary file is created (not insecurely anymore), removed and a symbolic link to this filename is created. An attacker could recreate the file before the symbolic link is created, forcing the display program to display different content. For the stable distribution (woody) this problem has been corrected in version 3.18-1.3. For the old stable distribution (potato) this problem has been corrected in version 3.9-1.3. For the unstable distribution (sid) this problem has been fixed in version 3.23-1. We recommend that you upgrade your mime-support 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.
