Acrobat Reader DC versions versions 2021.001.20150 (and earlier), 2020.001.30020 (and earlier) and 2017.011.30194 (and earlier) are affected by a Use After Free 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.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - Adobe Photoshop versions 21.2.6 (and earlier) and 22.3 (and earlier) are affected by a Buffer Overflow
    vulnerability when parsing a specially crafted JSX 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-2021-28548,
    CVE-2021-28549)

  - Acrobat Reader DC versions versions 2021.001.20150 (and earlier), 2020.001.30020 (and earlier) and
    2017.011.30194 (and earlier) are affected by a Use After Free 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-2021-28550)

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - Acrobat Reader DC versions versions 2021.001.20150 (and earlier), 2020.001.30020 (and earlier) and
    2017.011.30194 (and earlier) are affected by a Use After Free 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-2021-28550)

  - Tor before 0.3.5.10, 0.4.x before 0.4.1.9, and 0.4.2.x before 0.4.2.7 allows remote attackers to cause a
    Denial of Service (CPU consumption), aka TROVE-2020-002. (CVE-2020-10592)

  - Tor before 0.3.5.10, 0.4.x before 0.4.1.9, and 0.4.2.x before 0.4.2.7 allows remote attackers to cause a
    Denial of Service (memory leak), aka TROVE-2020-004. This occurs in circpad_setup_machine_on_circ because
    a circuit-padding machine can be negotiated twice on the same circuit. (CVE-2020-10593)

  - Tor before 0.4.5.7 allows a remote participant in the Tor directory protocol to exhaust CPU resources on a
    target, aka TROVE-2021-001. (CVE-2021-28089)

  - Tor before 0.4.5.7 allows a remote attacker to cause Tor directory authorities to exit with an assertion
    failure, aka TROVE-2021-002. (CVE-2021-28090)

The version of Adobe Acrobat installed on the remote macOS host is a version prior to 2017.011.30196, 2020.001.30025, or 2021.001.20155. It is, therefore, affected by multiple vulnerabilities.
