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 security flaws including heap buffer overflows and use-after-free vulnerabilities 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, 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 9.6 Extended Update Support 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 the client system running FreeRDP when connecting to a malicious RDP server. This could allow attackers to disrupt client operations or gain control over the affected system.
Mitigation Recommendations
Red Hat has released updated freerdp packages addressing these vulnerabilities as part of Red Hat Enterprise Linux 9.6 Extended Update Support. Users should apply the security update RHSA-2026:3037 promptly to remediate these issues. For detailed update instructions, refer to https://access.redhat.com/articles/11258. No additional mitigation steps are indicated by the vendor advisory.
