ALSA-2026:54485 — Important: freerdp security update

Affected: AlmaLinux:8: freerdp, AlmaLinux:8: freerdp-devel, AlmaLinux:8: freerdp-libs, AlmaLinux:8: libwinpr, AlmaLinux:8: libwinpr-devel

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: Arbitrary code execution via malicious RDP files (CVE-2026-64624) * FreeRDP: FreeRDP: Denial of Service via crafted WindowIcon async message (CVE-2026-67299) * FreeRDP: FreeRDP: HTTP Proxy Request Injection via Redirection (CVE-2026-67289) * FreeRDP: FreeRDP: Remote code execution or denial of service via audio input integer overflow (CVE-2026-68580)

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.

fkie_cve-2026-64624

FreeRDP before 3.28.0 treats lines beginning with forward slash in RDP files as raw command-line options, exposing the entire CLI parser surface to untrusted files. Attackers can craft malicious RDP files with /rdp2tcp, /cert:ignore, or /drive options to execute arbitrary commands, bypass certificate validation, or expose local filesystems without user interaction.

OESA-2026-3853 — freerdp security update

Affected: openEuler:24.03-LTS-SP4: freerdp

FreeRDP is a client implementation of the Remote Desktop Protocol (RDP) that follows Microsoft&apos;s open specifications. This package provides the client applications xfreerdp. Security Fix(es):

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.20.1, a global-buffer-overflow vulnerability was observed in FreeRDP's Base64 decoding path. The root cause is the implementation-defined signedness of the `char` type: on Arm/AArch64 builds, plain `char` is treated as unsigned, causing the guard condition `c <= 0` to potentially be optimized by the compiler into a simple `c != 0` check. Consequently, non-ASCII bytes (e.g., 0x80-0xFF) may bypass the intended range restriction and be used as an index into a global lookup table, resulting in out-of-bounds access. A malicious server can exploit this to trigger a client-side crash, leading to a denial of service.(CVE-2026-22858)

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.26.0, FreeRDP's planar bitmap decoder has an out-of-bounds heap write when decoding RLE planar data. In libfreerdp/codec/planar.c, freerdp_bitmap_decompress_planar() validates the X destination coordinate nXDst against the caller-provided destination stride (nDstStep) even when it is writing into the internal temp buffer pTempData. An attacker can bypass the check with a large nDstStep and a large nXDst, causing planar_decompress_plane_rle() to write past the end of pTempData. This…
