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.
Original advisory details:
Hanno BÃ¶ck discovered that NSS incorrectly handled certain division functions, possibly leading to cryptographic weaknesses. (CVE-2016-1938) This update also refreshes the NSS package to version 3.21 which includes the latest CA certificate bundle, and removes the SPI CA.
