CERT.
VERSIONS AFFECTED
DESCRIPTION
Multiple
vulnerabilities have been discovered in Internet Software Consortium (ISC)
BIND versions 4 and 8. In the first vulnerability, in BIND 8, a
remote buffer overflow can let an attacker execute arbitrary code without
having control over a DNS server. The second vulnerability, in BIND 4, is
also a buffer overflow that requires the attacker to have control over a
DNS server to execute arbitrary code. In the third vulnerability, also in
BIND 4, an attacker can use a format string issue to launch arbitrary
commands.
VENDOR RESPONSE
ISC
is aware of these issues and has released patches. BIND 4.9.8 and
8.2.3 address the vulnerabilities.
