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: Arbitrary code execution and denial of service via malicious server (CVE-2026-23883) * 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: Arbitrary code execution and denial of service via client-side heap buffer overflow (CVE-2026-23534) * 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
FreeRDP contains several critical security flaws including heap buffer overflows and use-after-free bugs that can be triggered by a malicious RDP server. These vulnerabilities (CVE-2026-23530, CVE-2026-23531, CVE-2026-23532, CVE-2026-23533, CVE-2026-23534, CVE-2026-23883, and CVE-2026-23884) may allow an attacker 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 released updated freerdp packages for Red Hat Enterprise Linux 10 and related variants to fix these issues.
Potential Impact
Successful exploitation of these vulnerabilities can result in denial of service or arbitrary code execution on systems running vulnerable versions of FreeRDP. This could allow a malicious RDP server to compromise the client system during an RDP session. The impact is significant given the potential for remote code execution.
Mitigation Recommendations
Red Hat has released updated freerdp packages addressing these vulnerabilities. Users of Red Hat Enterprise Linux 10 and related products should apply the security update as detailed in Red Hat advisory RHSA-2026:2222. Refer to https://access.redhat.com/articles/11258 for update instructions. Patch status is confirmed as fixed in these updated packages. No additional mitigations are specified by the vendor.
