critical Nessus Plugin ID 364432

Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1791538487 advisory.

 - Deployment of wrong handler vulnerability in Apache HTTP Server allows the target of some internal redirects from CGI programs to also be treated as CGI and executed. The target must already be in a directory enabled for CGI and have no other extension understood by mod_mime. This issue affects Apache HTTP Server: from 2.4.60 through 2.4.68. (CVE-2026-42356)

 - A memory calculation bug in mod_dav in Apache httpd 2.4.67 and earlier allows an attacker with permission to create WebDAV locks to crash server child processes. Users are recommended to upgrade to version 2.4.69, which fixes this issue (CVE-2026-42528)

 - NULL Pointer Dereference vulnerability in Apache HTTP Servers mod_heartmonitor over unicast listener. This issue affects Apache HTTP Server: from 2.4.0 through 2.4.68. (CVE-2026-46729)

 - Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache HTTP Server's mod_session_cookie module. When SessionCookieRemove changes across internal redirects, the session cookie may still be passed to a backend server. This issue affects Apache HTTP Server: from 2.4.0 through 2.4.68.
 (CVE-2026-47360)

 - Missing authentication checks in mod_auth_digest in Apache Software Foundation Apache HTTP Server before 2.4.69 on all platforms allows an unauthenticated remote client to cause a denial of service (forced re- authentication) via forged Authorization headers when Digest authentication is enabled with AuthDigestNcCheck . Users are recommended to upgrade to version 2.4.69, which fixes this issue.
 (CVE-2026-48005)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages based on the guidance in TuxCare advisory ALMALINUX9.2:CLSA-2026:1791538487.
