Summary

In order for this to be exploitable "non-stitched" ciphersuites must
be in use. Stitched ciphersuites are optimised implementations of
certain commonly used ciphersuites. Also the application must call
SSL_shutdown() twice even if a protocol error has occurred
(applications should not do this but some do anyway).
AEAD ciphersuites are not impacted.

For Debian 8 "Jessie", this problem has been fixed in version
1.0.1t-1+deb8u11.

We recommend that you upgrade your openssl packages.
