Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Input validation error
EUVDB-ID: #VU4347
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2016-9131
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause denial of service conditions.
The vulnerability exists due to assertion failure when processing DNS responses. A remote attacker can send a malformed response to an RTYPE ANY query, trigger assertion failure and cause denial of service.
Successful exploitation of the vulnerability will result in DoS attack against vulnerable application.
