Descriptions

Lack of validation on data read from guest memory in IntPeGetDirectory, IntPeParseUnwindData, IntLogExceptionRecord, IntKsymExpandSymbol and IntLixTaskDumpTree may lead to out-of-bounds read or it could cause DoS due to integer-overflor (IntPeGetDirectory), TOCTOU (IntPeParseUnwindData) or insufficient validations.

Una falta de comprobación en los datos leídos desde la memoria del invitado en IntPeGetDirectory, IntPeParseUnwindData, IntLogExceptionRecord, IntKsymExpandSymbol e IntLixTaskDumpTree, puede conllevar a una lectura fuera de límites o podría causar una DoS debido a un exceso de enteros (IntPeGetDirectory), una TOCTOU (IntPeParseUnwindData) o una comprobación insuficiente
