CVE-2023-50979 (https://github.com/weidai11/cryptopp/issues/1247):

Crypto++ (aka cryptopp) through 8.9.0 has a Marvin side channel during decryption with PKCS#1 v1.5 padding.

CVE-2023-50980 (https://github.com/weidai11/cryptopp/issues/1248):

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 (https://github.com/weidai11/cryptopp/issues/1249):

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.
