FreeBSD : openssl -- TLS extension parsing race condition (3042c33a-f237-11df-9d02-0018fe623f2b)
High Nessus Plugin ID 50627
SynopsisThe remote FreeBSD host is missing a security-related update.
DescriptionOpenSSL Team reports :
Rob Hulswit has found a flaw in the OpenSSL TLS server extension code parsing which on affected servers can be exploited in a buffer overrun attack.
Any OpenSSL based TLS server is vulnerable if it is multi-threaded and uses OpenSSL's internal caching mechanism. Servers that are multi-process and/or disable internal session caching are NOT affected.
In particular the Apache HTTP server (which never uses OpenSSL internal caching) and Stunnel (which includes its own workaround) are NOT affected.
SolutionUpdate the affected package.
