Name of the Vulnerable Software and Affected Versions OpenSSL versions prior to 0.9.8

Description The issue is related to the default configuration of OpenSSL, which uses MD5 for creating message digests. This makes it easier for remote attackers to forge certificates with a valid certificate authority signature. The problem arises because MD5 is not a cryptographically strong algorithm, allowing attackers to bypass security restrictions.

Recommendations For versions prior to 0.9.8, update to a version that uses a more cryptographically strong algorithm for creating message digests. As a temporary workaround, consider configuring OpenSSL to use a stronger algorithm for message digests until a patch is available.

Fix

Use of a Broken Cryptographic Algorithm
