CVE-2021-44187: Adobe Bridge SGI File Parsing Out-Of-Bounds Read Information Disclosure Vulnerability

Adobe Bridge version 11.1.2 (and earlier) and version 12.0 (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 SGI file.

Security readout for executives and security teams

Plain-English summary

Adobe Bridge can expose small amounts of sensitive memory when a user opens a malicious SGI image file. The business risk is limited because exploitation needs user interaction and the CVSS score is low, but affected creative or media-processing workstations should still be updated and trained not to open untrusted files.

Executive priority

Treat as routine patching priority unless Adobe Bridge users regularly process untrusted image files. It is not a crisis-level issue, but it can support broader exploitation by weakening memory protections.

Technical view

CVE-2021-44187 is a CWE-125 out-of-bounds read in Adobe Bridge SGI file parsing. Adobe Bridge 11.1.2 and earlier, and 12.0 and earlier, are listed as affected. Impact is limited to confidentiality and may help bypass mitigations such as ASLR.

Likely exposure

Exposure is most likely on endpoints running affected Adobe Bridge versions where users handle SGI or other image files from external or untrusted sources. The source bundle does not provide CPEs or deployment prevalence.

Exploitation context

The provided sources do not indicate active exploitation, and the CVE is not listed as KEV. Exploitation requires a victim to open a malicious SGI file locally, so phishing, file-sharing, or media workflow abuse are the plausible contexts.

Researcher notes

The source bundle supports affected version ranges, CWE-125 classification, low CVSS 3.0 score, local attack vector, required user interaction, and confidentiality-only impact. It does not include exploit proof, IOCs, or detailed fixed-version text beyond the Adobe advisory reference.

Mitigation direction

  • Review Adobe APSB22-03 and apply the vendor-recommended Bridge update.
  • Identify and prioritize affected Bridge 11.1.2 or earlier and 12.0 or earlier installations.
  • Restrict opening SGI files from untrusted sources where operationally feasible.
  • Reinforce user guidance for unexpected image attachments or downloads.

Validation and detection

  • Inventory Adobe Bridge versions across managed endpoints.
  • Confirm no endpoints remain on affected versions named in the CVE description.
  • Review endpoint telemetry for suspicious SGI files opened by Bridge users.
  • Verify vendor update status against Adobe APSB22-03 guidance.

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.
