CVE-2019-10952
An attacker could send a crafted HTTP/HTTPS request to render the web server unavailable and/or lead to remote code execution caused by a stack-based buffer overflow vulnerability.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (9.99%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
