Ubuntu 10.04 LTS / 10.10 / 11.04 / 11.10 : radvd vulnerabilities (USN-1257-1)

high Nessus Plugin ID 56776

Language:

Synopsis

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

Description

Vasiliy Kulikov discovered that radvd incorrectly parsed the ND_OPT_DNSSL_INFORMATION option. A remote attacker could exploit this with a specially crafted request and cause the radvd daemon to crash, or possibly execute arbitrary code. The default compiler options for affected releases should reduce the vulnerability to a denial of service. This issue only affected Ubuntu 11.04 and 11.10.
(CVE-2011-3601)

Vasiliy Kulikov discovered that radvd incorrectly filtered interface names when creating certain files. A local attacker could exploit this to overwrite certain files on the system, bypassing intended permissions. (CVE-2011-3602)

Vasiliy Kulikov discovered that radvd incorrectly handled certain lengths. A remote attacker could exploit this to cause the radvd daemon to crash, resulting in a denial of service. (CVE-2011-3604)

Vasiliy Kulikov discovered that radvd incorrectly handled delays when used in unicast mode, which is not the default in Ubuntu. If used in unicast mode, a remote attacker could cause radvd outages, resulting in a denial of service. (CVE-2011-3605).

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.

Solution

Update the affected radvd package.
