Apache HTTP Server: Mehrere Schwachstellen
Multiple vulnerabilities have been identified in the Apache HTTP Server (httpd) packages provided by Red Hat, specifically affecting the mod_proxy_ajp and mod_authn_socache modules. These include heap-based buffer over-reads, off-by-one out-of-bounds reads, null pointer dereference causing process crashes, and a critical heap-based buffer overflow that could allow arbitrary code execution. The vulnerabilities affect Red Hat Enterprise Linux 10 and related distributions. Red Hat has issued an important security advisory with updates addressing these issues. No CVSS scores are provided, but the advisory rates the impact as important.
AI Analysis
Technical Summary
This Red Hat security advisory addresses five vulnerabilities in the Apache HTTP Server's mod_proxy_ajp and mod_authn_socache modules. The issues include heap-based buffer over-reads and memory disclosure (CVE-2026-34059, CVE-2026-34032), off-by-one out-of-bounds reads (CVE-2026-33857), a NULL pointer dereference causing child process crashes (CVE-2026-33007), and a heap-based buffer overflow enabling arbitrary code execution (CVE-2026-28780). These vulnerabilities affect Red Hat Enterprise Linux 10 and related packages. The advisory provides updated packages that fix these issues. The vulnerabilities are rated as important by Red Hat Product Security.
Potential Impact
The vulnerabilities can lead to memory disclosure, process crashes, and potentially arbitrary code execution on affected systems running vulnerable versions of Apache HTTP Server. The most severe issue (CVE-2026-28780) allows arbitrary code execution via a heap-based buffer overflow in mod_proxy_ajp. This could enable an attacker to execute code with the privileges of the Apache server process. Other issues may cause denial of service or information leaks. No known exploits in the wild have been reported at this time.
Mitigation Recommendations
Red Hat has released updated httpd packages that address these vulnerabilities. Users of affected Red Hat Enterprise Linux 10 versions should apply the security update described in advisory RHSA-2026:21433 promptly. Detailed instructions for applying the update are available at https://access.redhat.com/articles/11258. No additional mitigation steps are indicated by the vendor advisory.
