  3. CVE-2026-2588
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.

Summary
  • (es) Las versiones de Crypt::NaCl::Sodium hasta la 2.001 para Perl tienen una falla de desbordamiento de entero en sistemas de 32 bits. Sodium.xs convierte un STRLEN (size_t) a unsigned long long al pasar un puntero de longitud a las funciones de libsodium. En sistemas de 32 bits, size_t es típicamente de 32 bits, mientras que un unsigned long long es de al menos 64 bits.
