The newest SNORTⓇ rule update is available now. 

Cisco Talos' latest ruleset includes SID 58276 (SID 300053 for Snort 3) to protect against the exploitation of a zero-day vulnerability in the Apache HTTP Server Project. An attacker could exploit CVE-2021-41773 to execute remote code on the targeted machine. As of earlier this week, this exploit has already been used in the wild.
