GHSA-3V45-F3VH-WG7M Oj: Stack Buffer Overflow in Oj.dump via Large Indent

Summary Oj.dump is vulnerable to a stack-based buffer overflow when a large :indent value is provided by the developer. fillindent in dump.h calls memsetindentstr, ' ', sizetopts-indent without validating the size. When opts-indent is set to INTMAX 2,147,483,647, the sizet cast preserves the larg...

Stack-based Buffer Overflow

Overview Affected versions of this package are vulnerable to Stack-based Buffer Overflow via the fillindent function when a very large value is provided to the indent option. An attacker can cause a crash by supplying an excessively large integer value, resulting in a stack buffer overflow during...
