A security vulnerability (CVE-2026-45700) in FreeRDP's planar bitmap decoder allows an out-of-bounds write that can lead to arbitrary code execution. This affects the xfreerdp client used to connect to RDP servers. Red Hat has issued a security update for Red Hat Enterprise Linux 9 and related variants to address this issue. The vulnerability is rated as high severity by Red Hat Product Security. The update fixes the flaw by correcting the out-of-bounds write condition.

Multiple vulnerabilities have been identified in FreeRDP, a Remote Desktop Protocol implementation used by the xfreerdp client in Red Hat Enterprise Linux 10 and related CodeReady Linux Builder packages. These include heap-buffer-overflow, use-after-free, out-of-bounds write, and crafted packet issues that could lead to remote code execution or denial of service. Red Hat has released security updates addressing these issues.

Red Hat has issued a security advisory for FreeRDP, a free implementation of the Remote Desktop Protocol client. Two vulnerabilities are addressed: a heap buffer overflow allowing arbitrary code execution via crafted pixel data (CVE-2026-33984) and a denial of service via specially crafted RDP messages (CVE-2026-33983). These vulnerabilities affect Red Hat Enterprise Linux 9 and related variants across multiple architectures. An update is available to remediate these issues.

FreeRDP, a free implementation of the Remote Desktop Protocol client, has two security vulnerabilities: a heap buffer overflow that allows arbitrary code execution via crafted pixel data (CVE-2026-33984) and a denial of service via specially crafted RDP messages (CVE-2026-33983). These issues affect various Red Hat Enterprise Linux 9.4 and 8.6 variants and related products. Red Hat has issued security updates to address these vulnerabilities.

Two security vulnerabilities were identified in FreeRDP, a free implementation of the Remote Desktop Protocol used by the xfreerdp client. The first is a heap buffer overflow (CVE-2026-33984) that could allow arbitrary code execution via crafted pixel data. The second is a denial of service vulnerability (CVE-2026-33983) triggered by specially crafted RDP messages. These issues affect FreeRDP packages in Red Hat Enterprise Linux 10.0 Extended Update Support and related CodeReady Linux Builder variants. Red Hat has issued an important security advisory and released updated packages to address these vulnerabilities.

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.
