Debian Security Advisory DSA-1522-1 security@debian.org
http://www.debian.org/security/ Florian Weimer
March 17, 2008 http://www.debian.org/security/faq
- ----------------------------------------------------------------------

Package : unzip
Vulnerability : programming error
Problem type : local
Debian-specific: no
CVE Id(s) : CVE-2008-0888

Tavis Ormandy discovered that unzip, when processing specially crafted
ZIP archives, could pass invalid pointers to the C library's free
routine, potentially leading to arbitrary code execution
(CVE-2008-0888).

For the stable distribution (etch), this problem has been fixed in
version 5.52-9etch1.

For the old stable distribution (sarge), this problem has been fixed
in version 5.52-1sarge5.

The unstable distribution (sid) will be fixed soon.

We recommend that you upgrade your unzip 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.
