The remote AIX host has a version of bind installed that is affected
by multiple denial of service vulnerabilities.
The version of bind installed on the remote AIX host is affected by
the following vulnerabilities :
- A denial of service vulnerability exists due to an error
in the lightweight resolver (lwres) protocol
implementation when resolving a query name that, when
combined with a search list entry, exceeds the maximum
allowable length. An unauthenticated, remote attacker
can exploit this to cause a segmentation fault,
resulting in a denial of service condition. This issue
occurs when lwresd or the the named 'lwres' option is
- A denial of service vulnerability exists within file
buffer.c due to improper construction of responses to
crafted requests. An unauthenticated, remote attacker
can exploit this, via a specially crafted query, to
cause an assertion failure, resulting in a daemon exit.
