OpenSSL TLS Server is prone to an overflow condition. The program fails to properly sanitize user-supplied input resulting in a heap overflow. With a specially crafted request, a remote attacker can cause a denial of service and potentially compromise an application using the library.
Upgrade to version 0.9.8p or 1.0.0b or higher, as they have been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
