"It was discovered that an old bug workaround in the SSL/TLS server
code allowed an attacker to modify the stored session cache
ciphersuite. This could possibly allow an attacker to downgrade the
ciphersuite to a weaker one on subsequent connections. (CVE-2010-4180)

It was discovered that an old bug workaround in the SSL/TLS server
code allowed an attacker to modify the stored session cache
ciphersuite. An attacker could possibly take advantage of this to
force the use of a disabled cipher. This vulnerability only affects
the versions of OpenSSL in Ubuntu 6.06 LTS, Ubuntu 8.04 LTS, and
Ubuntu 9.10. (CVE-2008-7270).

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."
