CVE-2026-109242 (GCVE-0-2026-109242)

Vulnerability from cvelistv5 – Published: 2026-10-12 16:04 – Updated: 2026-10-15 02:28

Title

FreeRDP before 3.0.0 and 3.6.0 before 3.32.0 Uninitialized Heap Disclosure via Progressive Codec Tile Upgrade

Summary

FreeRDP before 3.0.0 and 3.6.0 before 3.32.0 renders uninitialized heap memory from un-decoded progressive tiles because the tile->current buffer is allocated without zeroing. A malicious RDP server can send a crafted WBT_TILE_FIRST then WBT_TILE_UPGRADE sequence to paint heap bytes onscreen or abort the client process.

CVE-2026-110837 (GCVE-0-2026-110837)

Vulnerability from cvelistv5 – Published: 2026-10-14 22:52 – Updated: 2026-10-15 13:47

Title

FreeRDP 2.0.0 before 3.32.0 Heap Buffer Overflow via MP3 Audio Decoding

Summary

FreeRDP 2.0.0 before 3.32.0, when built with WITH_LAME=ON and WITH_DSP_FFMPEG=OFF, has a heap-based buffer overflow in freerdp_dsp_decode_mp3 because the right-channel PCM pointer is offset by a byte count treated as short elements. A malicious RDP server can send MP3 audio over rdpsnd so decoded samples cross the heap allocation, crashing the client.

Severity

6.1 (Medium)

CVE-2026-111880 (GCVE-0-2026-111880)

Vulnerability from cvelistv5 – Published: 2026-10-17 18:46 – Updated: 2026-10-19 16:40

Title

FreeRDP 2.0.0 before 3.32.0 Heap Out-of-Bounds Write via NTLM MIC Offset

Summary

FreeRDP versions from 2.0.0 before 3.32.0 contain a heap out-of-bounds write in the server hash-callback NTLM path that fails to validate the MIC offset. Unauthenticated attackers can send a crafted AUTHENTICATE_MESSAGE with a backward session-key offset and MIC offset to write 16 zero bytes beyond the allocation.

Severity

8.3 (High)
