Red Hat Security Advisory: freerdp security update
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 heap out-of-bounds write in RLE planar decode path (CVE-2026-26965) * freerdp: FreeRDP: Arbitrary code execution via heap buffer overflow in GDI surface pipeline (CVE-2026-26955) 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.
AI Analysis
Technical Summary
FreeRDP contains two critical security flaws: CVE-2026-26965, an arbitrary code execution vulnerability caused by a heap out-of-bounds write in the RLE planar decode path, and CVE-2026-26955, an arbitrary code execution vulnerability due to a heap buffer overflow in the GDI surface pipeline. Both vulnerabilities can lead to arbitrary code execution when processing RDP data. Red Hat has released updated freerdp packages for Red Hat Enterprise Linux 9 and associated builder variants to remediate these issues. The advisory references updated freerdp version 2.11.7-1.el9_7.3 packages as the fix.
Potential Impact
Successful exploitation of these vulnerabilities could allow an attacker to execute arbitrary code on systems running vulnerable versions of FreeRDP, potentially leading to full system compromise. The vulnerabilities stem from memory corruption issues in the RDP client implementation, specifically in the decoding and rendering pipelines. The Red Hat advisory rates the impact as Important (high severity). There are no known exploits in the wild at the time of the advisory.
Mitigation Recommendations
Red Hat has provided updated freerdp packages that fix these vulnerabilities. Users of Red Hat Enterprise Linux 9 and related CodeReady Linux Builder products should apply the security update described in RHSA-2026:6004 promptly. Detailed update instructions are available at https://access.redhat.com/articles/11258. No additional mitigations are specified by the vendor beyond applying the official patch.
