SGC Restart DoS Attack (CVE-2011-4619) ====================================== Support for handshake restarts for server gated cryptograpy (SGC) can be used in a denial-of-service attack. Thanks to Adam Langley <agl> for identifying and fixing this issue. Affected users should upgrade to OpenSSL 1.0.0f or 0.9.8s. Reference: http://openssl.org/news/secadv_20120104.txt
Seems to be the fix here: http://cvs.openssl.org/chngview?cn=21940 (0.9.8) http://cvs.openssl.org/chngview?cn=21927 (1.0.0)
