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 vulnerabilities that allow arbitrary code execution due to memory corruption issues: a heap out-of-bounds write in the RLE planar decode path (CVE-2026-26965) and a heap buffer overflow in the GDI surface pipeline (CVE-2026-26955). These vulnerabilities affect the xfreerdp client used to connect to RDP servers. Red Hat has issued an important security advisory (RHSA-2026:5939) providing updated freerdp packages for Red Hat Enterprise Linux 10 and related products to remediate these issues.
Potential Impact
Successful exploitation of these vulnerabilities could allow an attacker to execute arbitrary code on affected systems running vulnerable versions of FreeRDP. This could lead to compromise of the system where the freerdp client is used. No known exploits in the wild have been reported at this time.
Mitigation Recommendations
Red Hat has released updated freerdp packages that address these vulnerabilities. Users of Red Hat Enterprise Linux 10 and related products should apply the security update described in advisory RHSA-2026:5939 promptly. Detailed update instructions are available at https://access.redhat.com/articles/11258. No additional mitigation actions are indicated by the vendor advisory.
