Ubuntu 6.06 LTS / 8.04 LTS / 9.04 / 9.10 / 10.04 LTS : openssl vulnerability (USN-990-1)
Medium Nessus Plugin ID 49643
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionMarsh Ray and Steve Dispensa discovered a flaw in the TLS and SSLv3 protocols. If an attacker could perform a man in the middle attack at the start of a TLS connection, the attacker could inject arbitrary content at the beginning of the user's session. This update adds backported support for the new RFC5746 renegotiation extension and will use it when both the client and the server support it.
ATTENTION: After applying this update, a patched server will allow both patched and unpatched clients to connect, but unpatched clients will not be able to renegotiate. For more information, please refer to the following:
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.
SolutionUpdate the affected packages.
