Adobe Character Animator version 4.4 (and earlier) is affected by a memory corruption vulnerability when parsing a M4A file, potentially resulting in arbitrary code execution in the context of the current user. User interaction is required to exploit this vulnerability.

The version of Adobe Character Animator installed on the remote macOS host is prior to 4.4.2. It is, therefore, affected by multiple vulnerabilities as referenced in the APSB21-95 advisory.

  - Adobe Character Animator version 4.4 (and earlier) is affected by a Null pointer dereference vulnerability     when parsing a specially crafted file. An unauthenticated attacker could leverage this vulnerability to     achieve an application denial-of-service in the context of the current user. Exploitation of this issue     requires user interaction in that a victim must open a malicious file. (CVE-2021-40762, CVE-2021-40768)

  - Adobe Character Animator version 4.4 (and earlier) is affected by a memory corruption vulnerability when     parsing a WAF file, potentially resulting in arbitrary code execution in the context of the current user.
    User interaction is required to exploit this vulnerability. (CVE-2021-40763)

  - Adobe Character Animator version 4.4 (and earlier) is affected by a memory corruption vulnerability when     parsing a M4A file, potentially resulting in arbitrary code execution in the context of the current user.
    User interaction is required to exploit this vulnerability. (CVE-2021-40764, CVE-2021-40765)

  - Adobe Character Animator version 4.4 (and earlier versions) are affected by an out-of-bounds read     vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this     vulnerability to bypass mitigations such as ASLR. Exploitation of this issue requires user interaction in     that a victim must open a malicious file. (CVE-2021-40766, CVE-2021-40769)

  - Adobe Character Animator version 4.4 (and earlier) is affected by an Access of Memory Location After End     of Buffer vulnerability when parsing a specially crafted file. An unauthenticated attacker could leverage     this vulnerability to achieve an application denial-of-service in the context of the current user.
    Exploitation of this issue requires user interaction in that a victim must open a malicious file.
    (CVE-2021-40767)

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