The remote Ubuntu host is missing a security-related patch.
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
names when creating certain files. A local attacker could exploit this
to overwrite certain files on the system, bypassing intended
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).
Update the affected radvd package.
