Input validation error in OpenSSL - CVE-2016-2181

Vulnerability identifier: #VU1975

CSH Severity: Medium

CVSS v4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2016-2181

CWE-ID: CWE-20

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input within the Anti-Replay feature in the DTLS implementation when using a new epoch number in conjunction with a large sequence number. A remote attacker can perform a denial of service (DoS) attack (false-positive packet drops) via spoofed DTLS records.
