Name of the Vulnerable Software and Affected Versions OpenBSD versions 7.3 through 7.4 before errata 006 and 7.3 before errata 020 OpenBSD version 7.3 before errata 020

Description The issue is related to a NULL dereference when handling a malformed fastcgi request in the httpd(8) service. This can potentially allow a remote attacker to cause a denial of service.

Recommendations For OpenBSD versions 7.3 through 7.4 before errata 006, apply errata 006 to resolve the issue. For OpenBSD version 7.3 before errata 020, apply errata 020 to resolve the issue. As a temporary workaround, consider restricting access to the httpd(8) service until the errata can be applied.
