It was discovered that Bouncy Castle incorrectly handled certain crypto algorithms. A remote attacker could possibly use these issues to obtain sensitive information, including private keys.

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.
