MD5-based Signature in TLS/SSL Server X.509 Certificate

Among the options for a replacement of MD5 as a hash function:. If at all possible, you should increase the width of the hash for strong collision resistance, and use an at-least-256 bit member of the SHA-2, or perhaps the new SHA-3 family. The collision resistance of any 128-bit hash can be broken by educated brute force and about $2^{65}$ hashes (which is feasible for decently fast hashes Security Bulletin: : Vulnerability in MD5 Signature and Vulnerability Details. CVEID: CVE-2015-7575 DESCRIPTION: The TLS protocol could allow weaker than expected security caused by a collision attack when using the MD5 hash function for signing a ServerKeyExchange message during a TLS handshake. An attacker could exploit this vulnerability using man-in-the-middle techniques to impersonate a TLS server and obtain credentials. Codeigniter Object Injection Vulnerability via Encryption

Length extension attack - Wikipedia

A vulnerability in the implementation of Border Gateway Protocol (BGP) Message Digest 5 (MD5) authentication in Cisco NX-OS Software could allow an unauthenticated, remote attacker to bypass MD5 authentication and establish a BGP connection with the device. The vulnerability occurs because the BGP MD5 authentication is bypassed if the peer does

Coordinated Vulnerability Disclosure (also referred to as "CVD" or “responsible disclosure”) is widely regarded as the best way to responsibly protect customers from security vulnerabilities. CVD is based on two foundational concepts: when companies become aware of security vulnerabilities, (1) they work quickly, collaboratively, and
