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.
Vasiliy Kulikov discovered that radvd incorrectly filtered interface

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.
Update the affected radvd package.
