Ubuntu 10.04 LTS / 11.04 / 11.10 : nss vulnerability (USN-1540-1)

Medium Nessus Plugin ID 61569


The remote Ubuntu host is missing a security-related patch.


Kaspar Brand discovered a vulnerability in how the Network Security Services (NSS) ASN.1 decoder handles zero length items. If the user were tricked into opening a specially crafted certificate, an attacker could possibly exploit this to cause a denial of service via application crash.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected libnss3-1d package.
