1. Background
The Berkeley Internet Name Domain (BIND) is an implementation of the
Domain Name System (DNS).
CERT Advisory CA-98.05 describes three vulnerabilities in certain
versions of BIND. The first vulnerability, Inverse Query Buffer Overrun,
can be exploited by a remote attacker to gain root access to a DNS
name server. The second vulnerability, Denial-of-Service Vulnerabilities,
is concerned with buffer overflows that can be exploited to corrupt
DNS record data or crash the DNS server. SunOS(tm) and Solaris(tm) are
not vulnerable to third vulnerability described in the CERT advisory.
For more information about the vulnerabilities, please see the
CERT advisory at:
http://www.cert.org/ftp/cert_advisories/CA-98.05.bind_problems
A vulnerability has also been discovered in SunOS and Solaris's
implementation of BIND with their use of temporary files. This vulnerability
can be exploited to overwrite arbitrary files.
2. Affected Supported Versions
Solaris(tm) versions: 2.6, 2.6_x86, 2.5.1, 2.5.1_x86, 2.5, 2.5_x86,
2.4, 2.4_x86 and 2.3
SunOS(tm) versions: 4.1.4 and 4.1.3_U1
3. Recommendations
Sun recommends that you install the respective patches immediately on
vulnerable systems including both DNS clients and servers.
