Summary

OpenSSL is prone to multiple Denial of Service Vulnerabilities.

Insight

Insight

Multiple flaws are due to, - The library does not limit the number of buffered DTLS records with a future epoch. - An error when processing DTLS messages can be exploited to exhaust all available memory by sending a large number of out of sequence handshake messages. - A use-after-free error in the 'dtls1_retrieve_buffered_fragment()' function can be exploited to cause a crash in a client context.

Affected Software

Affected Software

OpenSSL version 0.9.8 to version 0.9.8k and version 1.0.x versions 1.0.0 Beta2 and prior.
