Description

Crypt::NaCl::Sodium versions through 2.001 for Perl has an integer overflow flaw on 32-bit systems. Sodium.xs casts a STRLEN (size_t) to unsigned long long when passing a length pointer to libsodium functions. On 32-bit systems size_t is typically 32-bits while an unsigned long long is at least 64-bits.

Integer Overflow or Wraparound

The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
