EUVD-2025-34779

An integer overflow vulnerability exists in the QuickJS regular expression engine libregexp due to an inconsistent representation of the bytecode buffer size. The regular expression bytecode is stored in a DynBuf structure, which correctly uses a $\textsize\textt$ an unsigned type, typically...

Integer Overflow or Wraparound

Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound in the jsbigintfromstring function when parsing strings with an excessively large number of digits. An attacker can cause a heap out-of-bounds write by supplying a crafted string input that triggers an...

CVE-2025-62496

The CVE refers to QuickJS: BigInt parsing in js_bigint_from_string. When converting a decimal string with an extremely large number of digits, the code computes n_bits as (n_digits × 27 + 7) / 8. For very large inputs (e.g., tens of millions of digits), this intermediate value overflows a 32-bit ...

CVE-2025-62495 Type confusion in string addition in QuickJS

An integer overflow vulnerability exists in the QuickJS regular expression engine libregexp due to an inconsistent representation of the bytecode buffer size. The regular expression bytecode is stored in a DynBuf structure, which correctly uses a $\textsize\textt$ an unsigned type, typically...

CVE-2025-62495

CVE-2025-62495 describes an integer overflow in QuickJS regExp (libregexp). The DynBuf storing regex bytecode uses size_t, but several internal routines cast the DynBuf size_t to a signed int, so very large/complex patterns can exceed 2^31 bytes. The result is a negative value used for offsets (e...
