Red Hat Security Advisory: freerdp security update
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. The xfreerdp client can connect to RDP servers such as Microsoft Windows machines, xrdp, and VirtualBox. Security Fix(es): * freerdp: FreeRDP: Heap buffer overflow leading to denial of service and potential code execution from a malicious server. (CVE-2026-23530) * freerdp: FreeRDP: Denial of Service and potential code execution via use-after-free vulnerability (CVE-2026-23884) * freerdp: FreeRDP: Heap buffer overflow leads to denial of service and potential code execution (CVE-2026-23533) * freerdp: FreeRDP: Heap buffer overflow via crafted RDPGFX surface updates leads to denial of service and potential code execution. (CVE-2026-23531) * freerdp: FreeRDP: Denial of Service and potential code execution via client-side heap buffer overflow (CVE-2026-23532) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
AI Analysis
Technical Summary
This advisory covers five security vulnerabilities in FreeRDP, including heap buffer overflows and use-after-free bugs (CVE-2026-23530, CVE-2026-23531, CVE-2026-23532, CVE-2026-23533, CVE-2026-23884). These flaws allow a malicious RDP server to cause denial of service or execute arbitrary code on the client system. The vulnerabilities affect the xfreerdp client used to connect to RDP servers such as Microsoft Windows, xrdp, and VirtualBox. Red Hat has issued an important security update for FreeRDP in Red Hat Enterprise Linux 7 Extended Lifecycle Support to fix these issues.
Potential Impact
Successful exploitation of these vulnerabilities can result in denial of service or remote code execution on systems running vulnerable FreeRDP clients. This could allow attackers controlling a malicious RDP server to compromise client machines. The vulnerabilities affect multiple heap buffer overflow and use-after-free conditions, which are critical memory safety issues.
Mitigation Recommendations
Red Hat has released security updates for FreeRDP in Red Hat Enterprise Linux 7 Extended Lifecycle Support that address these vulnerabilities. Users should apply the provided updates as described in the Red Hat advisory RHSA-2026:2714. Patch details and instructions are available at https://access.redhat.com/articles/11258. No alternative mitigations are specified; applying the official update is the recommended remediation.
