Name of the Vulnerable Software and Affected Versions quickjs-ng versions 0.9.0 and earlier QuickJS versions prior to 2025-04-26

Description The issue is related to an incorrect size calculation in JS ReadBigInt for a BigInt, leading to a heap-based buffer overflow.

Recommendations For quickjs-ng versions 0.9.0 and earlier, update to a version later than 0.9.0 to resolve the issue. For QuickJS versions prior to 2025-04-26, update to a version released after 2025-04-26 to fix the problem. As a temporary workaround, consider restricting the use of the JS ReadBigInt function for BigInt values until a patch is available.
