Cisco Talos has discovered a threat actor conducting several campaigns against government entities, military organizations and civilian users in Ukraine and Poland. We judge that these operations are very likely aimed at stealing information and gaining persistent remote access.

**According to the CVSS metric, successful exploitation of this vulnerability could lead to some loss of availability (A:L)? What does that mean for this vulnerability?** The performance can be interrupted and/or reduced, but the attacker cannot fully deny service.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** An attacker must send the user a malicious file and convince them to open it.
