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-use-after-free (CVE-2026-22856) * freerdp: FreeRDP heap-buffer-overflow (CVE-2026-22854) * freerdp: FreeRDP heap-buffer-overflow (CVE-2026-22852) * freerdp: FreeRDP: Denial of Service via FastGlyph parsing buffer overflow (CVE-2026-23732) * freerdp: FreeRDP: Denial of Service via use-after-free in AUDIN format renegotiation (CVE-2026-24676) * freerdp: FreeRDP has a heap-use-after-free in video_timer (CVE-2026-24491) * freerdp: FreeRDP has a NULL Pointer Dereference in rdp_write_logon_info_v2() (CVE-2026-23948) * freerdp: FreeRDP has a Heap-use-after-free in play_thread (CVE-2026-24684) * freerdp: FreeRDP has a heap-buffer-overflow in urb_select_interface (CVE-2026-24679) * freerdp: FreeRDP has a Heap-use-after-free in urb_select_interface (CVE-2026-24675) * freerdp: FreeRDP: Arbitrary code execution via crafted Remote Desktop Protocol (RDP) server messages (CVE-2026-31806) 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 multiple security flaws including heap-use-after-free (CVE-2026-22856, CVE-2026-24491, CVE-2026-24675, CVE-2026-24684), heap-buffer-overflow (CVE-2026-22852, CVE-2026-22854, CVE-2026-24679), NULL pointer dereference (CVE-2026-23948), denial of service via buffer overflow and use-after-free (CVE-2026-23732, CVE-2026-24676), and arbitrary code execution via crafted RDP server messages (CVE-2026-31806). These vulnerabilities impact the FreeRDP client implementation used in Red Hat Enterprise Linux 8.4 Extended Update Support and Advanced Update Support. Red Hat has released updated packages to fix these issues as detailed in advisory RHSA-2026:10735.
Potential Impact
The vulnerabilities collectively allow for potential denial of service conditions, crashes, and in the case of CVE-2026-31806, arbitrary code execution triggered by maliciously crafted RDP server messages. This could lead to compromise of systems running vulnerable FreeRDP clients. The issues affect heap memory management and pointer handling, increasing the risk of exploitation.
Mitigation Recommendations
Red Hat has released security updates for FreeRDP in Red Hat Enterprise Linux 8.4 Extended Update Support and Advanced Update Support. Users should apply the updated packages as described in Red Hat advisory RHSA-2026:10735 and the linked article https://access.redhat.com/articles/11258. These updates address all listed vulnerabilities. No additional mitigations are indicated by the vendor advisory.
