Debian Security Advisory DSA 308-1 security@debian.org

Package : gzip
Vulnerability : insecure temporary files
Problem-Type : local
Debian-specific: no
CVE Ids : CVE-1999-1332, CAN-2003-0367

Paul Szabo discovered that znew, a script included in the gzip
package, creates its temporary files without taking precautions to
avoid a symlink attack (CAN-2003-0367).

The gzexe script has a similar vulnerability which was patched in an
earlier release but inadvertently reverted.

For the stable distribution (woody) both problems have been fixed in
version 1.3.2-3woody1.

For the old stable distribution (potato) CAN-2003-0367 has been fixed
in version 1.2.4-33.2. This version is not vulnerable to
CVE-1999-1332 due to an earlier patch.

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you update your gzip 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.
