CVE-2021-44700: Adobe Illustrator JPEG File Parsing Out-Of-Bounds Read Information Disclosure Vulnerability

Adobe Illustrator versions 25.4.2 (and earlier) and 26.0.1 (and earlier) 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.

Security readout for executives and security teams

Plain-English summary

Adobe Illustrator could read past expected JPEG file data and expose small amounts of process memory. A user would need to open a malicious file. Business urgency is low, but the issue matters where Illustrator handles untrusted artwork or client submissions.

Executive priority

Handle through normal patch management unless affected users routinely open untrusted client files. Prioritize creative teams, marketing, and production endpoints first.

Technical view

CVE-2021-44700 is a CWE-125 out-of-bounds read in Adobe Illustrator JPEG parsing. Affected versions are Illustrator 25.4.2 and earlier, and 26.0.1 and earlier. Impact is limited confidentiality exposure and potential ASLR mitigation bypass. CVSS is 3.3, local attack vector, user interaction required.

Likely exposure

Exposure is most likely on designer or production workstations running the affected Illustrator versions, especially where users open externally supplied JPEG or Illustrator content.

Exploitation context

The bundle does not show KEV listing or active exploitation evidence. Exploitation requires user interaction: the victim must open a malicious file in Illustrator.

Researcher notes

Evidence in the provided bundle supports low-severity confidentiality impact, user interaction requirement, and no KEV signal. The bundle does not name fixed versions, so remediation should be tied to Adobe APSB22-02 rather than inferred.

Mitigation direction

  • Check Adobe APSB22-02 for official remediation guidance.
  • Update Illustrator through Adobe’s supported update channel.
  • Restrict opening untrusted design files on affected workstations.
  • Use endpoint controls to quarantine suspicious attachments or downloads.

Validation and detection

  • Inventory Illustrator versions across managed endpoints.
  • Flag installations at 25.4.2 or earlier, and 26.0.1 or earlier.
  • Confirm update status against Adobe APSB22-02 guidance.
  • Review endpoint alerts for suspicious files opened by Illustrator.

Out-of-bounds Read

Out-of-bounds Read represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
