CVE-2026-112892
Description
A flaw was found in Pillow. A remote attacker can cause a Denial of Service (DoS) by supplying a specially crafted Microsoft Paint (MSP) image file to an application that processes image pixels. Due to missing expansion limits during decompression, the run-length encoding (RLE) decoder expands image data into an unbounded memory buffer, resulting in memory exhaustion and application crashes.
Statement
This vulnerability is evaluated as an Important impact because remote unauthenticated actors can induce an application denial of service by consuming all host or container memory, bypassing standard decompression safety limits. In Red Hat deployments such as Red Hat OpenShift AI and Red Hat Quay, service ingestion workflows accepting user-submitted graphics could suffer process termination or node instability when decoding untrusted assets. Deployments that process only verified internal content or do not expose image analysis to external inputs face substantially lower operational risk.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
