CVE-2025-29489Public exploitNetwork attack vector

Service interruption via leaked morph-line allocations

Published Mar 27, 2025 · Updated Mar 28, 2025

Memory leak in libming 0.4.8 allows attackers to interrupt an application by supplying a crafted SWF file for parsing. The parseSWF_MORPHLINESTYLES function allocates 74,880 bytes while decoding a DefineMorphShape2 record but fails to release that allocation after parsing. Exploitation requires an application or user to process the file; repeated parsing consumes memory and can halt the affected process.
