CVE-2022-0778

CVE-2022-0778 Contributors Jeong Junsoo @jeongjunsoo Summary The CVE-2022-0778 vulnerability affects the BNmodsqrt function in OpenSSL that computes the modular square root of a prime number. When this function processes a maliciously crafted certificate that is not based on a prime number, an...

CVE-2022-0778

CVE-2022-0778 The discovered vulnerability triggers an infinite loop in the function BNmodsqrt of OpenSSL while parsing an elliptic curve key. This means that a maliciously crafted X.509 certificate can DoS any unpatched server. The core of the vulnerability is in the parsing of EC keys with poin...
