CVE-2025-46646
Description
A flaw was found in Artifex Ghostscript, specifically in the decode_utf8 function within base/gp_utf8.c. The issue arises from the mishandling of overlong UTF-8 encoding, which can lead to unexpected behavior when processing certain inputs. This flaw could allow an attacker to manipulate text encoding, potentially leading to incorrect processing of UTF-8 characters or unexpected application behavior, and exists because of an incomplete fix for CVE-2024-46954.
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).
The following CVSS metrics and score provided are preliminary and subject to review.
