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 security flaws: a heap buffer overflow (CVE-2026-33984) that can lead to 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 rated the update as Important and released patches for Red Hat Enterprise Linux 9 and its Extended Update Support versions. The advisory references updated freerdp packages version 2.11.7-7.el9_8.1 and related components.
Potential Impact
Successful exploitation of CVE-2026-33984 could allow an attacker to execute arbitrary code on the affected system via crafted pixel data in RDP sessions. CVE-2026-33983 could cause denial of service by crashing or disrupting the RDP client through maliciously crafted protocol messages. These vulnerabilities impact systems running the vulnerable freerdp client, potentially compromising system integrity or availability.
Mitigation Recommendations
Red Hat has released updated freerdp packages that address these vulnerabilities. Users of Red Hat Enterprise Linux 9 and related variants should apply the security update RHSA-2026:19349 promptly. Detailed update instructions are available at https://access.redhat.com/articles/11258. No additional mitigation actions are specified by the vendor advisory.
