Debian Security Advisory DSA 292-3 securityat_private
http://www.debian.org/security/ Martin Schulze
April 30th, 2003 http://www.debian.org/security/faq
- --------------------------------------------------------------------------
Package : mime-support
Vulnerability : insecure temporary file creation
Problem-Type : local
Debian-specific: no
I am awfully and sincerely sorry. Apparently, I wasn't able to assign
enough time to this issue and produced insufficiently tested
updates. I'll do my best not to repeat this.
This update fixes the second problem from the original advisory:
When run-mailcap is executed on a file with a potentially
problematic filename, a temporary file is created (not insecurely
anymore), removed and a symbolic link to this filename is created.
An attacker could recreate the file before the symbolic link is
created, forcing the display program to display different content.
For the stable distribution (woody) this problem has been corrected in
version 3.18-1.3.
For the old stable distribution (potato) this problem has been
corrected in version 3.9-1.3.
For the unstable distribution (sid) this problem has been fixed in
version 3.23-1.
We recommend that you upgrade your mime-support packages.
