NSS: insecure Diffie-Hellman key exchange
Published Oct 21, 2010

HIGHCVSS 2.0
EPSS 3.04%
Description
The SSL implementation in Mozilla Firefox before 3.5.14 and 3.6.x before 3.6.11, Thunderbird before 3.0.9 and 3.1.x before 3.1.5, and SeaMonkey before 2.0.9 does not properly set the minimum key length for Diffie-Hellman Ephemeral (DHE) mode, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a brute-force attack.
