There are 5 open security issues in bullseye.
5 issues left for the package maintainer to handle:
- CVE-2021-40530:
(needs triaging)
The ElGamal implementation in Crypto++ through 8.5 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.
- CVE-2022-48570:
(needs triaging)
Crypto++ through 8.4 contains a timing side channel in ECDSA signature generation. Function FixedSizeAllocatorWithCleanup could write to memory outside of the allocation if the allocated memory was not 16-byte aligned. NOTE: this issue exists because the CVE-2019-14318 fix was intentionally removed for functionality reasons.
- CVE-2023-50979:
(needs triaging)
Crypto++ (aka cryptopp) through 8.9.0 has a Marvin side channel during decryption with PKCS#1 v1.5 padding.
- CVE-2023-50980:
(needs triaging)
gf2n.cpp in Crypto++ (aka cryptopp) through 8.9.0 allows attackers to cause a denial of service (application crash) via DER public-key data for an F(2^m) curve, if the degree of each term in the polynomial is not strictly decreasing.
- CVE-2023-50981:
(needs triaging)
ModularSquareRoot in Crypto++ (aka cryptopp) through 8.9.0 allows attackers to cause a denial of service (infinite loop) via crafted DER public-key data associated with squared odd numbers, such as the square of 268995137513890432434389773128616504853.
