SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionIvan Nestlerode discovered that the Cryptographic Message Syntax (CMS) and PKCS #7 implementations in OpenSSL returned early if RSA decryption failed. This could allow an attacker to expose sensitive information via a Million Message Attack (MMA). (CVE-2012-0884)
It was discovered that an integer underflow was possible when using TLS 1.1, TLS 1.2, or DTLS with CBC encryption. This could allow a remote attacker to cause a denial of service. (CVE-2012-2333).
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 libssl0.9.8, libssl1.0.0 and / or openssl packages.
