Adobe After Effects version 18.2 (and earlier) is affected by an Our-of-bounds Read vulnerability when parsing a specially crafted file. An unauthenticated attacker could leverage this vulnerability to disclose sensitive memory information and cause a denial of service in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
