Crypto++

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.

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.

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.

Crypto++ (aka Cryptopp) 8.6.0 and earlier contains a timing leakage in MakePublicKey(). There is a clear correlation between execution time and private key length, which may cause disclosure of the length information of the private key. This might allow attackers to conduct timing attacks. NOTE: this report is disputed by the vendor and multiple third parties. The execution-time differences are intentional. A user may make a choice of a longer key as a tradeoff between strength and performance. In making this choice, the amount of information leaked to an adversary is of infinitesimal value
