This means that file managers, web browsers, and other programs which honor the mailcap file could automatically execute Oz programs downloaded from untrusted sources. Thus, a malicious Oz program could execute arbitrary code under the uid of a user running a MIME-aware client program if the user selected a file (for example, choosing a link in a web browser). For the stable distribution (woody) this problem has been fixed in version 1.2.3.20011204-3woody1. For the unstable distribution (sid) this problem has been fixed in version 1.2.5.20030212-2. We recommend that you update your mozart 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.
