Descripción técnica

FreeRDP before 3.32.2 contains a heap-based buffer overflow in the RD Gateway RPC client, where rpc_client_recv_fragment writes BIND_ACK and ALTER_CONTEXT_RESP fragments into a persistent PDU stream after checking only total capacity rather than remaining capacity from the current stream position. A malicious or compromised RD Gateway can send crafted RPC fragments with manipulated alloc_hint and frag_length values to overwrite client heap memory with attacker-controlled data, causing a crash or potentially arbitrary code execution.

CVE-2026-1219588.8 ALT

—

———FreeRDP through 3.32.1 has a heap out-of-bounds write in the RDPGFX client because the delete_surface callback truncates surface hash keys to 16 bits, leaving the surface table inconsistent so HashTable_GetKeys writes past its allocated key array. A malicious or man-in-the-middle RDP server can exploit this by creating surfaceId 0xFFFF, closing the RDPGFX channel, sending repeated DELETESURFACE PDUs, and then sending ENDFRAME or RESETGRAPHICS.5h CVE-2026-1219506.5 MED

—

———FreeRDP before 3.32.2 does not check the product of surface dimensions in gdi_CreateSurface when handling an RDPGFX CREATE_SURFACE PDU, causing an integer wrap and heap buffer overflow on 32-bit builds and an approximately 4 GiB allocation on 64-bit builds. A malicious RDP server can send a CREATE_SURFACE PDU with width and height 32766 to a connecting client to corrupt heap memory or cause a denial of service.5h CVE-2026-1219417.8 ALT

———libmt32emu before 2.8.4 contains a heap buffer overflow vulnerability in MidiStreamParserImpl::parseSysex that allows attackers to write past a heap allocation by supplying oversized unterminated SysEx messages. Attackers can feed more than 32768 SysEx data bytes through the mt32emu_parse_stream API via MIDI files, ports, or sequencer clients to corrupt heap memory and crash the application.8h CVE-2026-592677.8 ALT

———A crafted DXF document causes a heap buffer overflow in Draw in Apache OpenOffice 4.1.16 and earlier. This could cause a crash or otherwise a corruption of memory areas. Users are recommended to upgrade to version 4.1.17, which fixes this issue.5h CVE-2026-1145499.8 CRÍ

——0NoMachine nxwebrunner Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of NoMachine. Authentication is not required to exploit this vulnerability. The specific flaw exists within the web service, which listens on TCP port 4443 by default. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the service account. Was ZDI-CAN-30685.21h CVE-2026-1207757.2 ALT
