CVE-2026-56371: ImageMagick - Memory Leak in TXT File Processing via Texture Attribute

Published Jun 23, 2026
·
Updated

ImageMagick before 7.1.2-15 and 6.9.13-40 contains a memory leak in coders/txt.c when processing TXT files with texture attributes: the texture object allocated via ReadImage is not released when GetTypeMetrics fails, leaking memory each time a crafted TXT file with a texture attribute is processed.
