Description

This security bulletin contains information about 1 security vulnerability.


1) Spoofing attack (CVE-ID: CVE-2017-12132)

The vulnerability allows a remote attacker to perform spoofing attack and write arbitrary files on the target system.

The weakness exists in the DNS stub resolver due to soliciting large UDP responses from name servers, potentially simplifying off-path DNS spoofing attacks due to IP fragmentation, when EDNS support is enabled. A remote attacker can write arbitrary files.
