Résumé
Crypt::NaCl::Sodium versions through 2.002 for Perl has potential integer overflows
Description d'origine
La description telle que publiée par la source (souvent en anglais).
Crypt::NaCl::Sodium versions through 2.002 for Perl has potential integer overflows.
bin2hex, encrypt, aes256gcm_encrypt_afternm and seal functions do not check that output size will be less than SIZE_MAX, which could lead to integer wraparound causing an undersized output buffer.
Encountering this issue is unlikely as the message length would need to be very large.
For bin2hex() the bin_len would have to be > SIZE_MAX / 2 For encrypt() the msg_len would need to be > SIZE_MAX - 16U For aes256gcm_encrypt_afternm() the msg_len would need to be > SIZE_MAX - 16U For seal() the enc_len would need to be > SIZE_MAX - 64U
