Package        : gzip
Vulnerability  : insecure temporary files
Problem-Type   : local
Debian-specific: no
CVE ID         : CAN-2004-0970
BugTraq ID     : 11288

Trustix developers discovered insecure temporary file creation in
supplemental scripts in the gzip package which may allow local usersto overwrite files via a symlink attack.

For the stable distribution (woody) these problems have been fixed in
version 1.3.2-3woody3.

The unstable distribution (sid) is not affected by these problems.

We recommend that you upgrade your gzip package.
