Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 / 9.10 : openssl vulnerability (USN-884-1)

Medium Nessus Plugin ID 43898


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


It was discovered that OpenSSL did not correctly free unused memory in certain situations. A remote attacker could trigger this flaw in services that used SSL, causing the service to use all available system memory, leading to a denial of service.

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.
