Sourcefire VRT Advisory

Sun Java Web Start, Oracle Database Server, DNS, Spyware and Backdoor Updates

Synopsis:

The Sourcefire VRT is aware of vulnerabilities affecting Sun Java Web Start, Oracle Database Server and DNS implementations.

Details:

Sun Java Web Start Buffer Overflow (CVE-2008-3111):
Sun Java Web Start contains programming errors that may allow a remote attacker to execute code on a vulnerable system.

A rule to detect attacks targeting this vulnerability is included in this release and is identified with GID 1 and SID 13950.

Oracle Database Server Buffer Overflow (CVE-2008-2607):
Oracle Database Server contains programming errors that may allow a remote attacker to cause a Denial of Service (DoS) or a buffer overflow that may allow the attacker to execute code on a vulnerable system.

A rule to detect attacks targeting this vulnerability is included in this release and is identified with GID 1 and SID 13951.

DNS Cache Poisoning (CVE-2008-1447):
The DNS protocol as implemented in many distributions may allow a remote attacker to spoof DNS traffic via cache poisoning techniques. In addition to the detection provided by SID 13667 for this vulnerability, the Sourcefire VRT has added SIDs 13948 and 13949 to detect anomalous backscatter DNS traffic that would be generated during a DNS cache posioning attack.

Additionally, as a result of ongoing research, the Sourcefire VRT has added multiple rules to the spyware-put and backdoor rule sets to provide coverage for emerging threats from these technologies.
