QID 354102: Amazon Linux Security Advisory for Open Secure Sockets Layer (OpenSSL) : ALAS2022-2022-157

Two issues were found in OpenSSL 3.0. The first being a stack based buffer overflow, which is possible by sending an X.509 certificate with a specially crafted email address field. In the binaries provided in Amazon Linux 2022, this is restricted to overwriting bytes that are not referenced later in code execution (CVE-2022-3602). The second being a buffer overrun which can be triggered in X.509 certificate verification, and is restricted to CA signed certificates or applications continuing to proceed after failed validation (CVE-2022-3786). The potential impact from CVE-2022-3786 as present in Amazon Linux 2022 is to availability.
