Description

Rob Hulswit discovered a race condition in the OpenSSL TLS server extension parsing code when used within a threaded server. A remote attacker could trigger this flaw to cause a denial of service or possibly execute arbitrary code with application privileges. (CVE-2010-3864).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
