Process crash via invalid getWord memory read
Published Aug 16, 2022 · Updated Aug 3, 2024
Improper input handling in SWFMill 0.3.6 and earlier allows context-dependent attackers to crash the process via a crafted SWF file. SWF::Reader::getWord performs an invalid memory read while SWF::Header parses the file, causing a segmentation fault. The file must be processed locally, and the demonstrated consequence is termination of the command-line conversion process rather than a broader system outage.
