Red Hat Security Advisory: freerdp security update
Multiple security vulnerabilities have been identified in FreeRDP, a free implementation of the Remote Desktop Protocol (RDP) used in Red Hat Enterprise Linux 10.0 Extended Update Support and related products. These include heap-use-after-free, heap-buffer-overflow, NULL pointer dereference, denial of service, and arbitrary code execution issues. The vulnerabilities affect various components of FreeRDP, including audio, video, input events, and protocol message parsing. Red Hat has issued an important security advisory with updates to address these issues.
AI Analysis
Technical Summary
FreeRDP, an open-source RDP client used in Red Hat Enterprise Linux 10.0 EUS and related builds, contains multiple vulnerabilities such as heap-use-after-free (e.g., CVE-2026-22856, CVE-2026-24675), heap-buffer-overflow (e.g., CVE-2026-22852, CVE-2026-24679), NULL pointer dereference (CVE-2026-23948), denial of service via buffer overflow and use-after-free (CVE-2026-23732, CVE-2026-24676), and arbitrary code execution via crafted RDP server messages (CVE-2026-31806). These vulnerabilities affect various FreeRDP components including FastGlyph parsing, AUDIN format renegotiation, video timer, audio formats, input events, and USB interface selection. Red Hat has released updated packages to fix these issues as detailed in advisory RHSA-2026:6743.
Potential Impact
The vulnerabilities in FreeRDP can lead to denial of service conditions, crashes due to NULL pointer dereferences, memory corruption through heap buffer overflows and use-after-free bugs, and potentially arbitrary code execution when processing maliciously crafted RDP server messages. This could allow an attacker controlling an RDP server to compromise the client system running vulnerable FreeRDP versions. The security impact is rated as important by Red Hat.
Mitigation Recommendations
Red Hat has released updated FreeRDP packages addressing all listed vulnerabilities in Red Hat Enterprise Linux 10.0 Extended Update Support and related products. Users should apply these official security updates promptly. For detailed update instructions, refer to Red Hat advisory RHSA-2026:6743 and the article https://access.redhat.com/articles/11258. No additional mitigation steps are specified beyond applying the vendor-provided patches.
