Summary
openssl vulnerability
Details

It was discovered that OpenSSL incorrectly allocated memory buffers in the SSL/TLS state machine when receiving handshake data. A remote attacker could possibly use this issue to cause OpenSSL to consume excessive memory, leading to a denial of service. This issue is known as the "HollowByte" denial of service.
