Hi,

Nadhem Alfardan and Kenny Paterson have discovered a weakness in the handling
of CBC ciphersuites in SSL, TLS and DTLS. Their attack exploits timing
differences arising during MAC processing. Details of this attack can be
found at: http://www.isg.rhul.ac.uk/tls/

The issue has been fixed in upstream yaSSL 2.5.0:
http://www.yassl.com/yaSSL/Docs-cyassl-changelog.html

The generic protocol issue has been assigned CVE name CVE-2013-0169. The yaSSL
specific fix is known as CVE-2013-1623. Please mention these identifiers in 
the changelog.

Can you see to it that this issue is addressed in unstable and testing?


Cheers,
Thijs
