Severity:
Medium
Issue Overview:
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)
