Estado: ModificadaAlta (8.8)—

Adobe Illustrator version 25.2 (and earlier) is affected by a memory corruption vulnerability when parsing a specially crafted file. An unauthenticated attacker could leverage this vulnerability to achieve remote code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

CVSS

Probabilidad de explotación (EPSS)
