CVE-2026-8814 Details
Description
Versions of the package exifreader before 4.39.0 are vulnerable to Improper Handling of Highly Compressed Data (Data Amplification) due to decompressing PNG zTXt metadata without enforcing a built-in maximum decompressed output size. When asynchronous parsing is enabled, a crafted PNG file containing a highly compressed zTXt chunk can cause ExifReader to materialize a disproportionately large Comment value in memory.
A vulnerability exists in the ExifReader package, specifically in versions prior to 4.39.0, related to the improper management of highly compressed data. This issue arises because the library decompresses PNG zTXt metadata without applying a maximum limit on the size of the decompressed output. When asynchronous parsing is activated, a specially crafted PNG file with a heavily compressed zTXt chunk can lead ExifReader to generate an excessively large Comment value in memory, potentially causing memory exhaustion.
Users are advised to upgrade ExifReader to version 4.39.0 or higher.
