Debian: New NSS packages fix cryptographic weaknesses

Several vulnerabilities have been discovered in Mozilla’s Network Security Services (NSS) library. NSS recognizes a wildcard IP address in the subject’s Common Name field of an X.509 certificate, which might allow man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority. NSS does not properly set the minimum key length for Diffie-Hellman Ephemeral (DHE) mode, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a brute-force attack. Updated packages are available from security.debian.org.

CVE Id(s)      : CVE-2010-3170 CVE-2010-3173

Several vulnerabilities have been discovered in Mozilla's Network
Security Services (NSS) library.  The Common Vulnerabilities and
Exposures project identifies the following problems:

CVE-2010-3170
  NSS recognizes a wildcard IP address in the subject's Common
  Name field of an X.509 certificate, which might allow
  man-in-the-middle attackers to spoof arbitrary SSL servers via
  a crafted certificate issued by a legitimate Certification
  Authority.

CVE-2010-3173
  NSS does not properly set the minimum key length for
  Diffie-Hellman Ephemeral (DHE) mode, which makes it easier for
  remote attackers to defeat cryptographic protection mechanisms
  via a brute-force attack.

For the stable distribution (lenny), these problems have been fixed in
version 3.12.3.1-0lenny2.

For the unstable distribution (sid) and the upcoming stable
distribution (squeeze), these problems have been fixed in version
3.12.8-1.

We recommend that you upgrade your NSS 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.
