Red Hat Security Advisory: freerdp security update
Multiple vulnerabilities have been identified in FreeRDP, a free implementation of the Remote Desktop Protocol (RDP), affecting Red Hat Enterprise Linux 9.2 and related distributions. These include denial of service issues due to use-after-free, double free, endless blocking loops, crafted audio data, and a division-by-zero error. Additionally, there are memory safety issues such as heap-buffer-overflow and out-of-bounds reads leading to potential information disclosure. Red Hat has issued a security advisory with updates addressing these vulnerabilities.
AI Analysis
Technical Summary
The FreeRDP client used in Red Hat Enterprise Linux 9.2 contains multiple security flaws: CVE-2026-25952 (use-after-free causing 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 freerdp package version 2.4.1-6.el9_2.9 on multiple architectures. Red Hat has released updates to address these issues as detailed in advisory RHSA-2026:16483.
Potential Impact
The vulnerabilities primarily allow denial of service conditions through memory corruption and logic errors, and one vulnerability allows information disclosure via out-of-bounds heap reads. There is no indication of remote code execution or privilege escalation from the provided data. The impact is rated as moderate by Red Hat, reflecting the potential disruption of RDP client functionality and possible leakage of memory contents.
Mitigation Recommendations
Red Hat has released updated freerdp packages for Red Hat Enterprise Linux 9.2 and related variants that fix these vulnerabilities. Users should apply the security update referenced in advisory RHSA-2026:16483 as soon as possible. For detailed update instructions, refer to https://access.redhat.com/articles/11258. No additional mitigations are indicated by the vendor advisory.
