Hi,
the following CVE (Common Vulnerabilities & Exposures) id was
published for nss.

CVE-2009-2404[0]:
| Heap-based buffer overflow in a regular-expression parser in Mozilla
| Network Security Services (NSS) before 3.12.3, as used in Firefox,
| Thunderbird, SeaMonkey, Evolution, Pidgin, and AOL Instant Messenger
| (AIM), allows remote SSL servers to cause a denial of service
| (application crash) or possibly execute arbitrary code via a long
| domain name in the subject''s Common Name (CN) field of an X.509
| certificate, related to the cert_TestHostName function.

This issue is fixed in upstream NSS 3.12.3, so only the lenny version is
vulnerable.

CVE id in your changelog entry.
