Summary
ImageMagick has memory leak in msl encoder
Details
Memory leak exists in coders/msl.c. In the WriteMSLImage function of the msl.c file, resources are allocated. But the function returns early without releasing these allocated resources.
==78983== Memcheck, a memory error detector

==78983== Using Valgrind-3.22.0 and LibVEX; rerun with -h for copyright info
==78983==
==78983== 177,196 (13,512 direct, 163,684 indirect) bytes in 1 blocks are definitely lost in loss record 21 of 21

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
