CVE-2021-3517

There is a flaw in the xml entity encoding functionality of libxml2. An attacker who is able to supply a crafted file to be processed by an application linked with the affected functionality of libxml2 could trigger an out-of-bounds read. The most likely impact of this flaw is to application availability, with some potential impact to confidentiality and integrity if an attacker is able to use memory information to further exploit the application.

CVE-2022-0778

A flaw was found in OpenSSL. It is possible to trigger an infinite loop by crafting a certificate that has invalid elliptic curve parameters.
