PDF / .VIR static analysis report

Heuristics 4

• TrueType bitmap font + active content — CVE-2023-26369 related info CVE related PDF_CVE_2023_26369_RELATED
  PDF embeds a TrueType font with bitmap tables (EBDT/sbix/CBDT) alongside exploit delivery indicators — CVE-2023-26369 exploits the sfac_GetSbitBitmap function in Adobe's libCoolType for arbitrary code execution. This CVE was actively exploited in the wild, but this rule does not validate the malformed EBLC/EBDT primitive.
• PDF static-analysis soft budget exhausted low SCAN_INCOMPLETE
  The bounded PDF scanner skipped late sub-format walkers after the configured per-file soft deadline. Earlier findings remain valid.
• External URI info PDF_URI
  PDF contains an external URL action
• Embedded URL info EMBEDDED_URL
  One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
