openssl: Excessive time spent checking invalid RSA public keys

A flaw was found in OpenSSL. When the EVPPKEYpubliccheck function is called in RSA public keys, a computation is done to confirm that the RSA modulus, n, is composite. For valid RSA keys, n is a product of two or more large primes and this computation completes quickly. However, if n is a large...

ALPINE-CVE-2022-0778

The BNmodsqrt function, which computes a modular square root, contains a bug that can cause it to loop forever for non-prime moduli. Internally this function is used when parsing certificates that contain elliptic curve public keys in compressed form or explicit elliptic curve parameters with a...
