DSA-2123-1 nss -- several vulnerabilities

Date Reported:
01 Nov 2010
Affected Packages:
nss
Vulnerable:
Yes
Security database references:
In Mitre's CVE dictionary: CVE-2010-3170, CVE-2010-3173.
More information:

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.

Fixed in:

Debian GNU/Linux 5.0 (lenny)
