CVE-2022-48570

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 remov...

Amazon Linux AMI : python-ecdsa (ALAS-2023-1800)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2023-1800 advisory. An error-handling flaw was found in python-ecdsa before version 0.13.3. During signature decoding, malformed DER signatures could raise unexpected exceptions or no exceptions at all, which could...

CVE-2023-33242

Crypto wallets implementing the Lindell17 TSS protocol might allow an attacker to extract the full ECDSA private key by exfiltrating a single bit in every signature attempt 256 in total because of not adhering to the paper's security proof's assumption regarding handling aborts after a failed...

CVE-2023-33241

Crypto wallets implementing the GG18 or GG20 TSS protocol might allow an attacker to extract a full ECDSA private key by injecting a malicious pallier key and cheating in the range proof. Depending on the Beta parameters chosen in the protocol implementation, the attack might require 16 signature...
