QID 670972: EulerOS Security Update for Compat-Open Secure Sockets Layer (compat-OpenSSL) (EulerOS-SA-2021-2625)

The OpenSSL toolkit provides support for secure communications between machines. This version of OpenSSL package contains only the libraries and is provided for compatibility with previous releases and software that does not support compilation with OpenSSL-1.1. Security Fix(es): It was found that openssl assumed ASN.1 strings to be NUL terminated. A malicious actor may be able to force an application into calling openssl function with a specially crafted, non-NUL terminated string to deliberately hit this bug, which may result in a crash of the application, causing a Denial of Service attack, or possibly, memory disclosure. The highest threat from this vulnerability is to data confidentiality and system availability.(CVE-2021-3712)
