"The version of Adobe Illustrator installed on the remote Windows host is prior to 29.8.5, 30.2. It is, therefore,
affected by multiple vulnerabilities as referenced in the APSB26-18 advisory.

  - Illustrator versions 29.8.4, 30.1 and earlier are affected by an out-of-bounds write vulnerability that
    could result in arbitrary 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. (CVE-2026-21362, CVE-2026-27272)

  - Illustrator versions 29.8.4, 30.1 and earlier are affected by an Untrusted Search Path vulnerability that
    might allow attackers to execute arbitrary code in the context of the current user. Exploitation of this
    issue requires user interaction in that a victim must open a malicious file. (CVE-2026-21333)

  - Illustrator versions 29.8.4, 30.1 and earlier are affected by a Heap-based Buffer Overflow vulnerability
    that could result in arbitrary 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. (CVE-2026-27271)

  - Illustrator versions 29.8.4, 30.1 and earlier are affected by a Stack-based Buffer Overflow vulnerability
    that could result in arbitrary 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. (CVE-2026-27267)

  - Illustrator versions 29.8.4, 30.1 and earlier are affected by an Out-of-bounds Read vulnerability that
    could lead to memory exposure. An attacker could leverage this vulnerability to access sensitive
    information stored in memory. Exploitation of this issue requires user interaction in that a victim must
    open a malicious file. (CVE-2026-27268, CVE-2026-27270)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
