Ubuntu 6.06 LTS / 6.10 / 7.04 / 7.10 : openssl vulnerability (USN-534-1)

High Nessus Plugin ID 28140


The remote Ubuntu host is missing one or more security-related patches.


Andy Polyakov discovered that the DTLS implementation in OpenSSL was vulnerable. A remote attacker could send a specially crafted connection request to services using DTLS and execute arbitrary code with the service's privileges. There are no known Ubuntu applications that are currently using DTLS.

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.


Update the affected packages.
