[Bug] Stack-overflow in SQCompiler::Factor parsing deep unary expressions #312
Description
Description
We discovered a Stack-overflow vulnerability in the Squirrel compiler. The crash occurs when parsing a script containing a deeply nested sequence of unary operators (e.g., !!!!!!...).
The ASAN report shows an extremely deep recursion chain involving Factor, PrefixedExpr, and UnaryOP, eventually exhausting the stack and triggering a crash in SQLexer::Lex.
Environment
- OS: Linux x86_64
- Complier: Clang
- Build Configuration: Release mode with ASan enabled.
Vulnerability Details
- Target: Squirrel (squirrel-lang)
- Vulnerability Type: CWE-674: Uncontrolled Recursion
- Function: SQCompiler::Factor / SQCompiler::UnaryOP
- Location: squirrel/sqcompiler.cpp:863 (recurses to PrefixedExpr)
- Root Cause Analysis: The parser handles unary operators recursively.
// Example logic in sqcompiler.cpp
void SQCompiler::Factor() {
if (IsUnaryOp(token)) {
UnaryOP(op);
// UnaryOP calls PrefixedExpr, which calls Factor again
} ...
}
The PoC likely contains a long chain of unary operators (e.g., logical NOT ! or negation -). The compiler recurses for each operator without a depth limit check, leading to stack exhaustion.
Reproduce
- Build squirrel with Release optimization and ASAN enabled.
- Run with the crashing file:
./build/bin/sq repro
