The version of freerdp installed on the remote host is prior to 2.11.7-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3239 advisory.

    FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, a client-side heap     buffer overflow occurs in the FreeRDP client's AVC420/AVC444 YUV-to-RGB conversion path due to missing     horizontal bounds validation of H.264 metablock regionRects coordinates.  In yuv.c, the clamp() function     (line 347) only validates top/bottom against the surface/YUV height, but never checks left/right against     the surface width. When avc420_yuv_to_rgb (line 67) computes destination and source pointers using     rect->left, it performs unchecked pointer arithmetic that can reach far beyond the allocated surface     buffer. A malicious server sends a WIRE_TO_SURFACE_PDU_1 with AVC420 codec containing a regionRects entry     where left greatly exceeds the surface width (e.g., left=60000 on a 128px surface). The H.264 bitstream     decodes successfully, then yuv420_process_work_callback calls avc420_yuv_to_rgb which computes pDstPoint =     pDstData + rect->top * nDstStep + rect->left * 4, writing 16-byte SSE vectors 1888+ bytes past the     allocated heap region. This vulnerability is fixed in 3.24.0. (CVE-2026-29774)

    FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, a client-side heap out-     of-bounds read/write occurs in FreeRDP's bitmap cache subsystem due to an off-by-one boundary check in     bitmap_cache_put. A malicious server can send a CACHE_BITMAP_ORDER (Rev1) with cacheId equal to maxCells,     bypassing the guard and accessing cells[] one element past the allocated array. This vulnerability is     fixed in 3.24.0. (CVE-2026-29775)

    FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, Integer Underflow in     update_read_cache_bitmap_order Function of FreeRDP's Core Library This vulnerability is fixed in 3.24.0.
    (CVE-2026-29776)

    FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, a size_t underflow in     the IMA-ADPCM and MS-ADPCM audio decoders leads to heap-buffer-overflow write via the RDPSND audio     channel. In libfreerdp/codec/dsp.c, the IMA-ADPCM and MS-ADPCM decoders subtract block header sizes from a     size_t variable without checking for underflow. When nBlockAlign (received from the server) is set such     that size % block_size == 0 triggers the header parsing at a point where size is smaller than the header     (4 or 8 bytes), the subtraction wraps size to ~SIZE_MAX. The while (size > 0) loop then continues for an     astronomical number of iterations. This vulnerability is fixed in 3.24.0. (CVE-2026-31883)

    FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, division by zero in MS-     ADPCM and IMA-ADPCM decoders when nBlockAlign is 0, leading to a crash. In libfreerdp/codec/dsp.c, both     ADPCM decoders use size % block_size where block_size = context->common.format.nBlockAlign. The     nBlockAlign value comes from the Server Audio Formats PDU on the RDPSND channel. The value 0 is not     validated anywhere before reaching the decoder. When nBlockAlign = 0, the modulo operation causes a SIGFPE     (floating point exception) crash. This vulnerability is fixed in 3.24.0. (CVE-2026-31884)

    FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, there is an out-of-     bounds read in MS-ADPCM and IMA-ADPCM decoders due to unchecked predictor and step_index values from input     data. This vulnerability is fixed in 3.24.0. (CVE-2026-31885)

    FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, there is an out-of-     bounds read in freerdp_bitmap_decompress_planar when SrcSize is 0. The function dereferences *srcp (which     points to pSrcData) without first verifying that SrcSize >= 1. When SrcSize is 0 and pSrcData is non-NULL,     this reads one byte past the end of the source buffer. This vulnerability is fixed in 3.24.0.
