Ubuntu 8.04 LTS / 10.04 LTS / 10.10 / 11.04 : dbus vulnerability (USN-1176-1)

Medium Nessus Plugin ID 55700


The remote Ubuntu host is missing a security-related patch.


It was discovered that DBus did not properly validate the byte order of messages under certain circumstances. An attacker could exploit this to cause a denial of service via application crash or potentially obtain access to sensitive information.

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 dbus package.
