Red Hat Security Advisory: freerdp security update
Multiple vulnerabilities have been identified in FreeRDP, a free implementation of the Remote Desktop Protocol client used in Red Hat Enterprise Linux 9. 2. These include denial of service issues caused by use-after-free, double free, endless blocking loops, and crafted audio data, as well as memory safety issues such as heap-buffer-overflow, out-of-bounds read, and division-by-zero errors. Additionally, an information disclosure vulnerability via heap memory out-of-bounds read has been reported. Red Hat has issued a security advisory with updates addressing these vulnerabilities.
AI Analysis
Technical Summary
FreeRDP, used in Red Hat Enterprise Linux 9.2, contains multiple security vulnerabilities: CVE-2026-25952 (use-after-free leading to denial of service), CVE-2026-26986 (double free during disconnect causing denial of service), CVE-2026-27951 (endless blocking loop causing denial of service), CVE-2026-29775 (heap-buffer-overflow via out-of-bounds cacheId), CVE-2026-31885 (out-of-bounds read in ADPCM decoders due to missing bounds checks), CVE-2026-31884 (division-by-zero in ADPCM decoders when nBlockAlign is zero), CVE-2026-31883 (denial of service via crafted audio data), and CVE-2026-33985 (information disclosure via heap memory out-of-bounds read). These vulnerabilities affect the xfreerdp client connecting to RDP servers. Red Hat has released updated packages to address these issues.
Potential Impact
The vulnerabilities primarily allow denial of service conditions through memory corruption and logic errors, potentially disrupting RDP client operations. One vulnerability may lead to information disclosure via out-of-bounds heap memory reads. There is no indication of remote code execution or privilege escalation. No known exploits are reported in the wild at this time.
Mitigation Recommendations
Red Hat has released updated freerdp packages for Red Hat Enterprise Linux 9.2 that address these vulnerabilities. Users should apply the security update as described in Red Hat advisory RHSA-2026:16483 and the referenced article https://access.redhat.com/articles/11258. Applying these official patches is the recommended remediation. There is no indication that additional mitigations are required beyond updating to the fixed packages.
