There are 2 open security issues in buster.
2 issues left for the package maintainer to handle:
- CVE-2021-24115:
(needs triaging)
In Botan before 2.17.3, constant-time computations are not used for certain decoding and encoding operations (base32, base58, base64, and hex).
- CVE-2021-40529:
(needs triaging)
The ElGamal implementation in Botan through 2.18.1, as used in Thunderbird and other products, allows plaintext recovery because, during interaction between two cryptographic libraries, a certain dangerous combination of the prime defined by the receiver's public key, the generator defined by the receiver's public key, and the sender's ephemeral exponents can lead to a cross-configuration attack against OpenPGP.
You can find information about how to handle these issues in the security team's documentation.
