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.
