Adobe Photoshop versions 21.2.4 (and earlier) and 22.1.1 (and earlier) are affected by a Buffer Overflow vulnerability when parsing a specially crafted javascript file. An unauthenticated attacker could leverage this vulnerability to achieve 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.

The version of Adobe Photoshop installed on the remote macOS or Mac OS X host is prior to 21.2.5/22.2. It is, therefore, affected by multiple vulnerabilities as referenced in the apsb21-10 advisory.

  - Adobe Photoshop versions 21.2.4 (and earlier) and 22.1.1 (and earlier) are affected by an Out-of-bounds     Read vulnerability when parsing a specially crafted file. An unauthenticated attacker could leverage this     vulnerability to achieve 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-2021-21049,     CVE-2021-21050)

  - Adobe Photoshop versions 21.2.4 (and earlier) and 22.1.1 (and earlier) are affected by a Memory Corruption     vulnerability when parsing a specially crafted file. An unauthenticated attacker could leverage this     vulnerability to achieve 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-2021-21048)

  - Adobe Photoshop versions 21.2.4 (and earlier) and 22.1.1 (and earlier) are affected by a Buffer Overflow     vulnerability when parsing a specially crafted javascript file. An unauthenticated attacker could leverage     this vulnerability to achieve 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-2021-21051)

  - Adobe Photoshop versions 21.2.4 (and earlier) and 22.1.1 (and earlier) are affected by an Out-of-bounds     Write vulnerability. An unauthenticated attacker could leverage this vulnerability to achieve 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-2021-21047)

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