ImageMagick Memory Leak Vulnerability in MSL Coder

A memory leak vulnerability has been identified in ImageMagick versions prior to 7.1.2-15 and 6.9.13-40. The issue resides in the 'WriteMSLImage' function within 'coders/msl.c', where allocated resources are not properly released before the function exits. This oversight leads to a significant loss of memory, with Valgrind reporting over 177,000 bytes lost.

Impact

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

Remediation

Users can upgrade to ImageMagick versions 7.1.2-15 or 6.9.13-40 to address this vulnerability.
