Ubuntu 12.04 LTS : nss regression (USN-2903-2)

Medium Nessus Plugin ID 88928


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


USN-2903-1 fixed a vulnerability in NSS. An incorrect package versioning change in Ubuntu 12.04 LTS caused a regression when building software against NSS. This update fixes the problem.

We apologize for the inconvenience.

Hanno Bock discovered that NSS incorrectly handled certain division functions, possibly leading to cryptographic weaknesses.

This update also refreshes the NSS package to version 3.21 which includes the latest CA certificate bundle, and removes the SPI CA.

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-dev package.
