Summary
Tyson Smith and Jed Davis discovered that NSS incorrectly handled memory. A
remote attacker could use this issue to cause NSS to crash, resulting in a
denial of service, or possibly execute arbitrary code.
This update refreshes the NSS package to version 3.23 which includes
the latest CA certificate bundle. As a security improvement, this update
also modifies NSS behaviour to reject DH key sizes below 1024 bits,
preventing a possible downgrade attack.
