Debian: DSA-1701-1: New OpenSSL packages fix cryptographic weakness

Date 12 Jan 2009
Posted By LinuxSecurity Advisories
It was discovered that OpenSSL does not properly verify DSA signatures on X.509 certificates due to an API misuse, potentially leading to the acceptance of incorrect X.509 certificates as genuine (CVE-2008-5077).

Package        : openssl, openssl097
Vulnerability  : interpretation conflict
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2008-5077
Debian Bug     : 511196

It was discovered that OpenSSL does not properly verify DSA signatures
on X.509 certificates due to an API misuse, potentially leading to the
acceptance of incorrect X.509 certificates as genuine (CVE-2008-5077).

For the stable distribution (etch), this problem has been fixed in
version 0.9.8c-4etch4 of the openssl package, and version
0.9.7k-3.1etch2 of the openssl097 package.

For the unstable distribution (sid), this problem has been fixed in
version 0.9.8g-15.

The testing distribution (lenny) will be fixed soon.

We recommend that you upgrade your OpenSSL packages.

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.
