SSL: SSL Certificate Signed With MD5 Hash(1)

This signature detects SSL certificates that have been signed using the MD5 hash algorithm. Known weaknesses in the MD5 algorithm allow for certificates signed with it to be spoofed by attackers. The certificate detected by this signature could potentially be illegitimate. All certificates in the signing chain are checked.

Extended Description

mod_ssl in Apache 2.0.50 and earlier allows remote attackers to cause a denial of service (CPU consumption) by aborting an SSL connection in a way that causes an Apache child process to enter an infinite loop.
