DEBIAN-CVE-2026-54502

Oj Optimized JSON is a JSON parser and Object marshaller packaged as a Ruby gem. In versions prior to 3.17.2, 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...

GHSA-C8RR-9GXC-JPRV UltraJSON has an integer overflow handling large indent leads to buffer overflow or infinite loop

Summary ujson.dumps crashes the Python interpreter segmentation fault when the product of the indent parameter and the nested depth of the input exceeds INT32MAX. It can also get stuck in an infinite loop if the indent is a large negative number. Both are caused by an integer overflow/underflow...
