Technical summary

The supplied official source corpus identifies CVE-2015-2545 as a Microsoft Office vulnerability tied to malformed EPS files. The CISA KEV entry marks it as known exploited and directs defenders to apply updates per vendor instructions. No additional technical details, impact classification, or exploitation mechanics are provided in the supplied corpus, so this debrief limits itself to that confirmed scope.

Defensive priority

High. CISA has placed this CVE in the Known Exploited Vulnerabilities catalog, which is a strong signal to accelerate remediation and verify patch deployment on all affected Microsoft Office installations.

Recommended defensive actions

  • Apply Microsoft-supplied updates or mitigations for Microsoft Office as soon as possible.
  • Inventory endpoints and servers that have Microsoft Office installed to confirm exposure.
  • Review document-handling workflows that may involve EPS content and restrict untrusted files until remediation is complete.
  • Confirm patch compliance through endpoint management and reporting.
  • Monitor CISA KEV updates and vendor guidance for any additional instructions.

Evidence notes

Evidence is limited to the supplied official sources: the CISA KEV record names the issue 'Microsoft Office Malformed EPS File Vulnerability,' marks it as known exploited, lists Microsoft Office as the affected product, and provides a required action to apply vendor updates. The supplied corpus does not include CVSS, exploit details, or a fuller impact statement, so no unsupported severity claims are made here.
