Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 : cyrus-sasl2 vulnerability (USN-790-1)

High Nessus Plugin ID 39515


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


James Ralston discovered that the Cyrus SASL base64 encoding function could be used unsafely. If a remote attacker sent a specially crafted request to a service that used SASL, it could lead to a loss of privacy, or crash the application, resulting in 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.
