Category:	Ubuntu Local Security Checks
Title:	Ubuntu: Security Advisory (USN-1257-1)
Summary:	The remote host is missing an update for the 'radvd' package(s) announced via the USN-1257-1 advisory.
Description:	Summary: The remote host is missing an update for the 'radvd' package(s) announced via the USN-1257-1 advisory. Vulnerability Insight: 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) Affected Software/OS: 'radvd' package(s) on Ubuntu 10.04, Ubuntu 10.10, Ubuntu 11.04, Ubuntu 11.10. Solution: Please install the updated package(s). CVSS Score: 7.5 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
