Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the readBytes or readString functions in BitStreamReader when the setBitPosition process receives an overflowed value, bypassing bounds checks. An attacker can cause a segmentation fault and potentially crash the application by supplying crafted input that triggers the reading of an excessive number of bytes from a small buffer.
