CVE-2022-23196: 
Adobe Illustrator vulnerability analysis and mitigation

Adobe Illustrator versions 25.4.3 (and earlier) and 26.0.2 (and earlier) are affected by an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. The vulnerability was discovered in late 2021 and publicly disclosed on February 8, 2022. This security issue affects both Windows and MacOS platforms (Adobe Advisory).

The vulnerability (CVE-2022-23196) is specifically a Memory Leak vulnerability that exists in the decoding of CorelDraw Drawing (CDR) files in Adobe Illustrator. The issue is caused by a malformed CDR file, which triggers an Out of Bounds memory access due to an improper bounds check. The vulnerability has been assigned a CVSS v3.1 base score of 5.5 (Medium) with the vector string CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N (NVD, Fortinet Blog).

An attacker could leverage this vulnerability to bypass mitigations such as ASLR (Address Space Layout Randomization) and perform unintended memory reads, potentially leading to sensitive memory data leaks. The exploitation requires user interaction, specifically opening a malicious CDR file (NVD, Fortinet Blog).

Adobe has released security patches to address this vulnerability. Users are strongly advised to update to the latest version of Adobe Illustrator. Fortinet has also implemented protective measures through their IPS signature to help defend against potential exploits (Adobe Advisory, Fortinet Blog).
