USN-1029-1: OpenSSL vulnerabilities

Packages

openssl -

Details

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)
