Test ID:	1.3.6.1.4.1.25623.1.0.70987
Category:	Ubuntu Local Security Checks
Title:	Ubuntu USN-1257-1 (radvd)
Summary:	NOSUMMARY
Description:	Description: The remote host is missing an update to radvd announced via advisory USN-1257-1. Details: 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) Solution: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.10: radvd 1:1.8-1ubuntu0.1 Ubuntu 11.04: radvd 1:1.7-1ubuntu0.1 Ubuntu 10.10: radvd 1:1.6-1ubuntu0.1 Ubuntu 10.04 LTS: radvd 1:1.3-1.1ubuntu0.1 http://www.securityspace.com/smysecure/catid.html?in=USN-1257-1
