ImageMagick Memory Leak Vulnerability in WriteASHLARImage Function

A memory leak vulnerability has been identified in ImageMagick versions prior to 7.1.2-15, specifically within the WriteASHLARImage function in coders/ashlar.c. The vulnerability arises because the function allocates a structure but fails to properly release the memory when an exception occurs, leading to a potential memory leak.

Impact

Exploitation of this vulnerability causes a memory leak, where allocated memory is not released properly, potentially leading to increased memory usage and degradation of application performance over time.

Remediation

Users can upgrade to ImageMagick version 7.1.2-15 or later to address this vulnerability.
