In OpenSSL 1.1.0 prior to 1.1.0d, if a malicious server supplies bad parameters for a DHE or ECDHE key exchange then this can result in the client attempting to dereference a NULL pointer leading to a client crash. This could be exploited in a Denial of Service attack.

OpenSSL pushes trio of DoS-busting patches

The Register • Richard Chirgwin • 31 Jan 2017

One was fixed before anyone realised it was a security issue, so be careful when applying

OpenSSL's released patches for a trio of denial-of-service bugs. The first (CVE-2017-3731), turned up by Google's Robert Święcki, only affects SSL/TLS servers running on 32-bit hosts. Depending on the cipher the host is using, a truncated packet crashes the system by triggering an out-of-bounds read. It's version-specific: under OpenSSL 1.1.0 the relevant cipher is CHACHA20/POLY1305 and it's fixed in 1.1.0d. In OpenSSL 1.0.2, RC4-MD5 (which should have been disabled) is the target, and it's fi...
