Synopsis
The remote Ubuntu host is missing one or more security-related patches.Description
It was discovered that OpenSSL incorrectly handled return codes from the bn_wexpand function calls. A remote attacker could trigger this flaw in services that used SSL to cause a denial of service or possibly execute arbitrary code with application privileges. This issue only affected Ubuntu 6.06 LTS, 8.04 LTS, 9.04 and 9.10.(CVE-2009-3245)
It was discovered that OpenSSL incorrectly handled certain private keys with an invalid prime. A remote attacker could trigger this flaw in services that used SSL to cause a denial of service or possibly execute arbitrary code with application privileges. The default compiler options for affected releases should reduce the vulnerability to a denial of service. (CVE-2010-2939).
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.
