Package: gthumb Version: 3:3.11.2-0.1 Tags: patch, security Dear Maintainer, the gthumb package has mailcap entries with quoted %-escapes. That is considered unsafe. Proper escaping should be left to the programs using the entry.
This Lintian tag is triggered: https://lintian.debian.org/tags/quoted-placeholder-in-mailcap-entry.html See also grave bug #930908, which was recently closed because "a Lintian test already exists": https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=930908 I'm using the "security" tag because the affected rules in combination with certain mail user agents (or document openers) are the cause of a shell command injection vulnerability. If you need more information let me know. Thanks, MNZ
