1) NULL pointer dereference
EUVDB-ID: #VU27061
Risk: Medium
CVSSv3.1: 6.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2020-1967
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the SSL_check_chain() function during or after a TLS 1.3 handshake. A remote attacker can send an invalid or unrecognised signature algorithm and perform a denial of service (DoS) attack.
