For completeness we include the advisory text: Colin Phipps discovered several problems in mime-support, that contains support programs for the MIME control files 'mime.types' and 'mailcap'. When a temporary file is to be used it is created insecurely, allowing an attacker to overwrite arbitrary under the user id of the person executing run-mailcap, most probably root. Additionally the program did not properly escape shell escape characters when executing a command. This is unlikely to be exploitable, though. For the stable distribution (woody) these problems have been fixed in version 3.18-1.2. For the old stable distribution (potato) these problems have been fixed in version 3.9-1.2. For the unstable distribution (sid) these problems have been fixed in version 3.22-1 (same as DSA 292-1). 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.
