apache2 regression

Published Mar 9, 2026 · Updated Apr 22, 2026

Summary

USN-7968-1 fixed vulnerabilities in Apache HTTP Server. The update
introduced a regression in mod_md where the MDStapleOthers setting was
ignored which resulted in OCSP being broken for some domains. This update
fixes the problem.

We apologize for the inconvenience.

Original advisory details:

It was discovered that the Apache HTTP Server incorrectly handled failed
ACME certificate renewals. This could result in renewal attempts to be
repeated without delays, possibly leading to a denial of service.
(CVE-2025-55753)

Anthony Parfenov discovered that the Apache HTTP Server would pass the
query string to cmd directives when configured with Server Side Includes
(SSI) enabled and mod_cgid. An attacker could possibly use this issue to
execute arbitrary code. (CVE-2025-58098)

Mattias Åsander discovered that the Apache HTTP Server incorrectly
neutralized certain environment variables. This could result in
unexpectedly superseding variables calculated by the server for CGI
programs. (CVE-2025-65082)

Mattias Åsander discovered that the Apache HTTP Server incorrectly
handled AllowOverride FileInfo configurations when using mod_userdir with
suexec. An attacker with access to use the RequestHeader directive in
htaccess can cause some CGI scripts to run under an unexpected userid.
(CVE-2025-66200)
