Red Hat Security Advisory: Satellite 6.18.6 Async Update
Red Hat Satellite is a system management solution that allows organizations to configure and maintain their systems without the necessity to provide public Internet access to their servers or other client systems. It performs provisioning and configuration management of predefined standard operating environments. Security Fix(es): * python3.12-pillow: Pillow: Out-of-bounds Write via Specially Crafted PSD Image (CVE-2026-25990) * candlepin: com.mchange/c3p0: c3p0: Arbitrary Code Execution via deserialization of crafted objects (CVE-2026-27830) * dynflow-utils: Root.Chmod can follow symlinks out of the root (CVE-2026-32282)
AI Analysis
Technical Summary
This advisory covers three distinct vulnerabilities fixed in Red Hat Satellite 6.18.6 for RHEL 9. CVE-2026-25990 involves an out-of-bounds write in the python3.12-pillow library triggered by specially crafted PSD images. CVE-2026-27830 is an arbitrary code execution vulnerability in the candlepin component's c3p0 library due to unsafe deserialization of crafted objects. CVE-2026-32282 is a flaw in dynflow-utils where the Root.Chmod function can follow symlinks outside the intended root directory, potentially leading to unauthorized file permission changes. Red Hat has released updated packages to remediate these issues and recommends applying this update after ensuring all prior errata are applied.
Potential Impact
Successful exploitation of these vulnerabilities could allow attackers to execute arbitrary code (CVE-2026-27830), cause memory corruption via out-of-bounds write (CVE-2026-25990), or escalate privileges by manipulating file permissions through symlink traversal (CVE-2026-32282). These impacts can compromise system integrity and security of Red Hat Satellite environments.
Mitigation Recommendations
Red Hat has released Red Hat Satellite 6.18.6 which includes fixes for these vulnerabilities. Users should apply this update promptly after confirming all previous errata are installed. Detailed update instructions are available in the official Red Hat Satellite documentation. No additional mitigation steps are indicated by the vendor advisory.
