Summary
Kaitai Struct: compiler vulnerable to denial-of-service (DoS)
Details
Kaitai Struct: compiler provided by Kaitai team contains SnakeYAML library version 1.25, which is used in parsing .ksy files. SnakeYAML version 1.25 expands recursive aliases unlimitedly (CWE-674), hence Katai Struct: compiler is vulnerable to a denial-of-service (DoS) attack by Billion Laughs Attack. Taichi Kotake of Sterra Security Co.,Ltd. / Akatsuki Games Inc. reported this vulnerability to IPA. JPCERT/CC coordinated with the developer under Information Security Early Warning Partnership.
