"The version of Adobe Photoshop installed on the remote macOS or Mac OS X host is prior to 26.11.8/27.11. It is,
therefore, affected by multiple vulnerabilities as referenced in the apsb26-158 advisory.

  - Photoshop Desktop is affected by an Incorrect Authorization vulnerability that could result in arbitrary
    code execution in the context of the current user. An attacker could exploit this vulnerability to execute
    arbitrary code. Exploitation of this issue requires user interaction in that a victim must open a
    malicious file. Scope is changed. (CVE-2026-95639)

  - Photoshop Desktop is 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-2026-100111, CVE-2026-100112, CVE-2026-104346, CVE-2026-104347,
    CVE-2026-95637, CVE-2026-95641, CVE-2026-96521, CVE-2026-96522, CVE-2026-96523, CVE-2026-97312)

  - Photoshop Desktop is 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-2026-104348, CVE-2026-95638)

  - Photoshop Desktop is affected by a NULL Pointer Dereference vulnerability that could result in an
    application denial-of-service. An attacker could exploit this vulnerability to crash the application,
    leading to a denial-of-service condition. Exploitation of this issue requires user interaction in that a
    victim must open a malicious file. (CVE-2026-105896, CVE-2026-95640)

  - Photoshop Desktop is affected by an Integer Overflow or Wraparound 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-2026-83661, CVE-2026-95636)

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