CVE-2026-27596
Description
A flaw was found in Exiv2, a C++ library and command-line utility for managing image metadata. An out-of-bounds read vulnerability exists within the preview component. This flaw can be triggered when an attacker processes a specially crafted image file using Exiv2 with a specific command-line argument, such as '-pp'. Successful exploitation of this vulnerability typically leads to a denial of service (DoS) due to the application crashing.
Statement
This is a LOW impact flaw in Exiv2. The vulnerability in the preview component is only triggered when the exiv2 utility is executed with the -pp command-line argument.
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.
