Package        : nss
Vulnerability  : several
Problem type   : remote
Debian-specific: no
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.
