Red Hat Security Advisory: freerdp security update
A security vulnerability (CVE-2026-45700) in FreeRDP's planar bitmap decoder allows an out-of-bounds write that can lead to arbitrary code execution. This affects the xfreerdp client used to connect to RDP servers. Red Hat has issued a security update for Red Hat Enterprise Linux 9 and related variants to address this issue. The vulnerability is rated as high severity by Red Hat Product Security. The update fixes the flaw by correcting the out-of-bounds write condition.
AI Analysis
Technical Summary
CVE-2026-45700 is an out-of-bounds write vulnerability in the planar bitmap decoder component of FreeRDP, a free implementation of the Remote Desktop Protocol. This flaw allows an attacker to execute arbitrary code by exploiting the memory corruption caused by the out-of-bounds write. Red Hat Product Security has released an important security update for FreeRDP packages in Red Hat Enterprise Linux 9 and its variants, including CodeReady Linux Builder and extended update support versions across multiple architectures (x86_64, aarch64, s390x, ppc64le). The advisory references updated package versions (e.g., freerdp-2.11.7-7.el9_8.4) that contain the fix.
Potential Impact
Successful exploitation of this vulnerability could allow an attacker to execute arbitrary code on the affected system via the FreeRDP planar bitmap decoder. This could lead to full compromise of the system running the vulnerable FreeRDP client. The vulnerability affects multiple architectures and variants of Red Hat Enterprise Linux 9. No known exploits in the wild have been reported at the time of the advisory.
Mitigation Recommendations
Red Hat has released updated FreeRDP packages that fix the out-of-bounds write vulnerability. Users should apply the security update RHSA-2026:37207 or later for Red Hat Enterprise Linux 9 and related variants to remediate this issue. Details on applying the update are available at https://access.redhat.com/articles/11258. No additional mitigations are specified or required beyond applying the official patch.
