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 allows arbitrary code execution via crafted pixel data (CVE-2026-33984) * FreeRDP: FreeRDP: Denial of Service via specially crafted Remote Desktop Protocol messages (CVE-2026-33983) 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 two vulnerabilities: a heap buffer overflow (CVE-2026-33984) that enables arbitrary code execution when processing crafted pixel data, and a denial of service vulnerability (CVE-2026-33983) triggered by specially crafted Remote Desktop Protocol messages. These vulnerabilities affect the xfreerdp client used to connect to RDP servers. Red Hat Product Security has released an update for Red Hat Enterprise Linux 10 to remediate these issues.
Potential Impact
Successful exploitation of CVE-2026-33984 could allow an attacker to execute arbitrary code on the affected system, potentially leading to full system compromise. CVE-2026-33983 could cause a denial of service, disrupting the availability of the affected service. Both vulnerabilities impact the security and stability of systems running vulnerable versions of FreeRDP.
Mitigation Recommendations
Red Hat has released an official security update for FreeRDP in Red Hat Enterprise Linux 10 that addresses these vulnerabilities. Users should apply the update as detailed in the Red Hat advisory (RHSA-2026:8458) and the referenced article https://access.redhat.com/articles/11258. No additional mitigation is required beyond applying this update.
