Adobe Premiere Pro: Buffer underwrite leads to code execution
Summary
Adobe Premiere Pro versions 26.5.2 and earlier and 25.6.6 and earlier on Windows and macOS contain a buffer underwrite (CWE-124). If a user opens a malicious project or media file, an attacker can execute arbitrary code with the rights of the logged-in user. The attack is not directly reachable from the internet and requires the victim to open the file.
Affected
- Adobe Premiere Pro 26.5.2 and earlier (Windows and macOS)
- Adobe Premiere Pro 25.6.6 and earlier (Windows and macOS)
Fixed in
- Adobe Premiere Pro 26.5.3 for the 26.x line
- Adobe Premiere Pro 27.0 for the 25.x line
Workaround
- No vendor workaround is known.
- Until the update is applied, do not open project or media files from untrusted sources.
Exploitation
- Adobe is not aware of any exploits in the wild for the issues in bulletin APSB26-101.
- CISA SSVC assessment: exploitation none, automatable no.
- Not listed in CISA KEV according to the consulted trackers.
- No public proof-of-concept found at the time of research.
Our recommendation
- Update Adobe Premiere Pro to 26.5.3 or 27.0 via the Creative Cloud update process.
- Prioritise workstations that handle media or project files from external freelancers or unknown senders.
- Warn users not to open unexpected project or media files from email or shared downloads.
- Monitor for updates and new exploit reports.
