Ubuntu 6.06 LTS / 7.10 / 8.04 LTS / 8.10 : openssl vulnerability (USN-750-1)

Medium Nessus Plugin ID 36907


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


It was discovered that OpenSSL did not properly validate the length of an encoded BMPString or UniversalString when printing ASN.1 strings.
If a user or automated system were tricked into processing a crafted certificate, an attacker could cause a denial of service via application crash in applications linked against OpenSSL.

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.
