CVE-2022-23195: 
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 discovered in late 2021. The vulnerability, identified as CVE-2022-23195, was reported by Fortinet security researchers and officially disclosed on February 8, 2022. This security flaw specifically affects the 'ReaderforCGM' plugin when processing Computer Graphics Metafile (CGM) files (Adobe Advisory, Fortinet Research).

The vulnerability is classified as an out-of-bounds read vulnerability that occurs during the decoding of Computer Graphics Metafile (CGM) files in Adobe Illustrator. The issue specifically exists in the 'ReaderforCGM' plugin and is caused by a malformed CGM file, which triggers an Out of Bounds Read 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).

The exploitation of this vulnerability could lead to the disclosure of sensitive memory information. An attacker could potentially leverage this vulnerability to bypass security mitigations such as Address Space Layout Randomization (ASLR). The vulnerability could result in unintended memory reads, potentially leading to memory data leaks (Fortinet Research).

Adobe has released security patches to address this vulnerability. Users of Adobe Illustrator 2022 (version 26.0.2 and earlier) and Adobe Illustrator 2021 (version 25.4.3 and earlier) are advised to apply the latest security updates as soon as possible. The fix was included in Adobe's February 2022 security update (Adobe Advisory).
