Debian: mime-support insecure tmp file creation vulnerability
Summary
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 3.18-1.1.
For the old stable distribution (potato) these problems have been
fixed in version 3.9-1.1.
For the unstable distribution (sid) these problems have been
fixed in version 3.22-1.
We recommend that you upgrade your mime-support packages.
