Deeper analysis
Acrobat Reader DC versions 22.001.20085 and earlier, 20.005.3031x and earlier, and 17.012.30205 and earlier contain a use-after-free flaw (CWE-416) in the font-processing code path. The vulnerability carries a CVSS 3.0 base score of 7.8 and can result in arbitrary code execution in the context of the current user when a specially crafted document is handled.
An attacker can trigger the issue only by supplying a malicious file that the victim must open; no other interaction or elevated privileges are required. Successful exploitation grants the attacker the ability to execute arbitrary code with the privileges of the logged-in user on the affected Windows or macOS system.
The official Adobe security bulletin APSB22-16, available at https://helpx.adobe.com/security/products/acrobat/apsb22-16.html, addresses the flaw and supplies the corresponding patched builds for each affected track.
