aiootp@0.7.1 vulnerabilities

aiootp is an aiootp - an asynchronous pseudo-one-time-pad based crypto and anonymity library.

Affected versions of this package are vulnerable to Insufficient Entropy such that the top-level '(a)csprng' functions were found to be unsafe in concurrent code, leading to the possibility of producing identical outputs from distinct calls if run in quick succession from concurrently running threads & co-routines.

Note: This vulnerability does not effect users of the library which are not running it in multiple concurrent threads or co-routines.

Upgrade aiootp to version 0.22.0 or higher.

aiootp is an aiootp - an asynchronous pseudo-one-time-pad based crypto and anonymity library.

Affected versions of this package are vulnerable to Cryptographic Issues. The new StreamHMAC class ensures the user must contend with ciphertext validation even when using the *_encipher, *_decipher & *_xor Comprende generators. All usages of the generics.py hmac functions are impacted by a reordering of the key & argument within those functions to more closely mirror the reasoning behind the HMAC spec. The main a/*_keys generators used by the pseudo one time pad cipher has been altered to patch a flaw in its design described in CHANGES.rst. The database classes filenames have switched from a base36 encoding to base38.

Upgrade aiootp to version 0.18.0 or higher.

aiootp is an aiootp - an asynchronous pseudo-one-time-pad based crypto and anonymity library.

Affected versions of this package are vulnerable to Cryptographic Issues. If an adversary can get a user to reveal the value returned by the hmac method when fed the tag file's filename & the salt used for that encrypted tag, then they could deduce the decryption key for the tag. This version check is here only for backwards compatibility & will be removed on the next update.

Upgrade aiootp to version 0.18.1 or higher.

aiootp is an aiootp - an asynchronous pseudo-one-time-pad based crypto and anonymity library.

Affected versions of this package are vulnerable to Cryptographic Issues. The HMAC verifiers on ciphertexts did not include the salt or pid values when deriving the HMAC. This associated data can therefore be changed to cause a party to decrypt a past ciphertext with a salt or pid of an attacker's choosing.

Upgrade aiootp to version 0.17.0 or higher.

aiootp is an aiootp - an asynchronous pseudo-one-time-pad based crypto and anonymity library.

Affected versions of this package are vulnerable to Information Disclosure. xor & axor functions that define the one-time-pad cipher had a vulnerability where it could leak <1-bit of plaintext. The issue was in the way keys were built, where the multiplicative products of two key segments were xor'd together. This led to keys being slightly more likely to be positive integers, meaning the final bit had a greater than 1/2 probability of being a 0.

Upgrade aiootp to version 0.13.0 or higher.
