The xfreerdp client can connect to RDP servers such as Microsoft Windows machines, xrdp, and VirtualBox. Security Fix(es): * freerdp: FreeRDP: Arbitrary code execution via heap out-of-bounds write in RLE planar decode path (CVE-2026-26965) * freerdp: FreeRDP: Arbitrary code execution via heap buffer overflow in GDI surface pipeline (CVE-2026-26955) 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 (CVE-2026-26965 and CVE-2026-26955) that enable arbitrary code execution through heap out-of-bounds write in the RLE planar decode path and heap buffer overflow in the GDI surface pipeline. These vulnerabilities are present in the xfreerdp client, which connects to RDP servers such as Microsoft Windows, xrdp, and VirtualBox. Red Hat Product Security has released an update for Red Hat Enterprise Linux 10.0 Extended Update Support to fix these issues. The advisory references bugzilla entries BZ-2442959 and BZ-2443132 for the respective CVEs and provides updated package versions (freerdp-3.10.3-3.el10_0.3) to remediate the vulnerabilities.
Potential Impact
Successful exploitation of these vulnerabilities could allow an attacker to execute arbitrary code on the affected system via the FreeRDP client. This could lead to compromise of the client system when connecting to malicious or compromised RDP servers. The vulnerabilities are rated with high severity by Red Hat, indicating significant security impact.
Mitigation Recommendations
Red Hat has released an official security update for FreeRDP in Red Hat Enterprise Linux 10.0 Extended Update Support. Users should apply the updated packages (freerdp-3.10.3-3.el10_0.3 and related) as detailed in the Red Hat advisory RHSA-2026:5936 and the referenced article https://access.redhat.com/articles/11258.
