    <Details xml:lang="en:us" source="Red Hat">
A flaw was found in simdjson, a JSON parsing library. An integer overflow vulnerability in the document-builder API, specifically within the `string_builder::escape_and_append()` function, can occur when processing very large input strings on systems with limited `size_t` width, such as 32-bit builds. This overflow can lead to incorrect buffer size calculations and insufficient memory allocation. Consequently, this may result in out-of-bounds memory reads during SIMD (Single Instruction, Multiple Data) operations, potentially causing information disclosure, memory corruption, or malformed JSON output.
