Ärende: [SECURITY] [DSA 292-2] New mime-support packages fix temporary file race conditions
------------------------------------------------------------

Debian Security Advisory DSA 292-2 security@debian.org
http://www.debian.org/security/ Martin Schulze
April 23rd, 2003 http://www.debian.org/security/faq
- --------------------------------------------------------------------------
Package : mime-support
Vulnerability : insecure temporary file creation
Problem-Type : local
Debian-specific: no
Unfortunately yesterday's update for mime-support did not exactly work
as expected, which requires an update. 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.
