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 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 has released security updates for Red Hat Enterprise Linux 10.0 Extended Update Support to mitigate 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 denial of service, disrupting the availability of the affected service or system. Both vulnerabilities pose significant security risks to systems running vulnerable versions of FreeRDP.
Mitigation Recommendations
Red Hat has released updated freerdp packages for Red Hat Enterprise Linux 10.0 Extended Update Support that address these vulnerabilities. Users should apply the security update as detailed in Red Hat advisory RHSA-2026:11333 and the referenced article https://access.redhat.com/articles/11258. No additional mitigations are specified by the vendor. Patch status is confirmed as fixed in the updated packages.
