Description

This security bulletin contains information about 1 vulnerability.


1) Integer underflow (CVE-ID: CVE-2026-29776)

CWE-ID: CWE-191 - Integer underflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to integer underflow in update_read_cache_bitmap_order() in libfreerdp/core/orders.c when processing a crafted bitmap cache order from the network. A remote attacker can send a specially crafted RDP update that causes excessive memory allocation and process termination to cause a denial of service.

User interaction is required, and exploitation occurs in the client while handling server-supplied RDP data.
