This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.
Description
UltraJSON (aka ujson) through 5.1.0 has a stack-based buffer overflow in Buffer_AppendIndentUnchecked (called from encode). Exploitation can, for example, use a large amount of indentation.

** DISPUTED ** UltraJSON (aka ujson) 4.0.2 through 5.0.0 has a stack-based buffer overflow in Buffer_AppendIndentUnchecked (called from encode). NOTE: multiple third parties dispute whether this is a confirmed finding, because the event that caused the Reproducer Testcase to stop indicating a buffer overflow was a change to the AFLplusplus project (5525f8c9ef8bb879dadd0eb942d524827d1b0362), not a change to the UltraJSON project.
