Descriptions

Adobe Illustrator versions 26.3.1 (and earlier) and 25.4.6 (and earlier) are affected by an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass mitigations such as ASLR. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Adobe Illustrator. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of embedded fonts. Crafted data in a font can trigger a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
