CVE-2026-93599: Integer Underflow (Wrap or Wraparound)

rustls-webpki through 0.103.12 and 0.104.0-alpha releases before 0.104.0-alpha.7 contains a reachable panic in bitstringflags in src/der.rs. The input guard fails to reject a named-bit BIT STRING whose content is exactly 0x00 zero padding bits and no data bytes, so rawbits.len - 1 underflows on t...

Integer Underflow (Wrap or Wraparound)

Overview Affected versions of this package are vulnerable to Integer Underflow Wrap or Wraparound via the bsonnewfrombuffer function. An attacker can cause a crash by supplying crafted BSON data with a zero-length prefix, leading to a heap out-of-bounds read when the function fails to validate th...
