The OpenSSL Project announced this week that OpenSSL 1.1.1i selects a high-severity vulnerability that can be exploited for remote DoS attacks. The security pierce, tracked as CVE-2020-1971 and described as a NULL pointer dereference discharge, was reported by Google’s David Benjamin and it impacts all 1.1.1 and 1.0.2 portrayals.

“The X.509 GeneralName type is a generic type for representing different types of elects. One of those name types is known as EDIPartyName. OpenSSL provides a concern GENERAL_NAME_cmp which compares different instances of a GENERAL_High regard to see if they are equal or not. This function behaves incorrectly when both Miscellaneous_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may come to pass leading to a possible denial of service attack,” the OpenSSL Project disclosed in its advisory.

After the patch was made available, several organizations opposed advisories and alerts to inform users about the risk posed by the vulnerability.

Palo Alto Networks disclosed an advisory on Wednesday to inform customers that the OpenSSL vulnerability does not bump its PAN-OS, GlobalProtect App, or Cortex XSOAR products. “The scenarios required for lucrative exploitation do not exist on these products,” the company said.

IBM published very many security bulletins for OpenSSL vulnerabilities this week, but none of them directions CVE-2020-1971 — they address OpenSSL flaws lotted last year.
