Description

The Server Gated Cryptography (SGC) implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly handle handshake restarts, which allows remote attackers to cause a denial of service (CPU consumption) via unspecified vectors.

Solution(s)

  • http-openssl-0_9_8-upgrade-0_9_8_s
  • http-openssl-1_0_0-upgrade-1_0_0_f
