- →Target mod_http2 module in Apache HTTP Server versions 2.4.24 and 2.4.25 — a specially crafted HTTP/2 request triggers a NULL pointer dereference and crashes the httpd child process ↗
- →Monitor for unexpected httpd child process crashes, particularly following HTTP/2 requests — the crash vector is a remote attacker sending a specially crafted HTTP/2 request to the mod_http2 module ↗
- →Review upstream patch commits for mod_http2 NULL pointer dereference fix to understand the exact code path triggered — trunk fix at commit 672187c168b94b562d8065e08e2cad5b00cdd0e3, backported to 2.4 branch at bc6ad1ef31f2c9e8f5eb453293a4b9caceaa191d ↗
- ·Vulnerability only affects Apache HTTP Server versions 2.4.24 and 2.4.25 with mod_http2 enabled; all Red Hat Enterprise Linux 5/6/7 and JBoss packages are listed as Not Affected, suggesting mod_http2 was not shipped or enabled in those builds ↗
- ·The vulnerability requires HTTP/2 to be active (mod_http2 loaded and H2/H2C enabled in configuration); deployments without HTTP/2 support enabled are not exploitable ↗
