Technical Analysis

TigerVNC, a suite of VNC servers and clients used in Red Hat Enterprise Linux 9, includes the xorg-x11-server component which was found vulnerable to three security issues: heap buffer overread/data leakage in ProcXIGetSelectedEvents (CVE-2024-31080) and ProcXIPassiveGrabDevice (CVE-2024-31081), and a use-after-free in ProcRenderAddGlyphs (CVE-2024-31083). These vulnerabilities could potentially lead to data leakage or memory corruption. Red Hat has released security updates for xorg-x11-server to fix these vulnerabilities across multiple architectures and Extended Update Support versions of RHEL 9.

Potential Impact

The identified vulnerabilities could allow an attacker to cause heap buffer overreads leading to data leakage or trigger use-after-free conditions causing memory corruption. This could impact the confidentiality and stability of systems running vulnerable versions of xorg-x11-server within TigerVNC on Red Hat Enterprise Linux 9. No known exploits in the wild have been reported at this time.

Mitigation Recommendations

A security update fixing these vulnerabilities is available from Red Hat. Users should apply the provided patches as detailed in the Red Hat advisories RHSA-2024:9122 and RHSA-2024:2036. The vendor has rated the impact as Moderate to Important and recommends updating to the fixed versions. Refer to https://access.redhat.com/articles/11258 for update instructions. No additional mitigation steps are indicated by the vendor.
