Heap-based buffer overflow in Adobe Flash Player before 13.0.0.302 and 14.x through 18.x before 18.0.0.203 on Windows and OS X and before 11.2.202.481 on Linux, Adobe AIR before 18.0.0.180, Adobe AIR SDK before 18.0.0.180, and Adobe AIR SDK & Compiler before 18.0.0.180 allows attackers to execute arbitrary code via unspecified vectors, a different vulnerability than CVE-2015-3135 and CVE-2015-4432.

  • Trigger is a malformed FLV file loaded via a SWF (LoadMP4.swf) — monitor Flash Player loading FLV files with anomalous indexing, particularly via query-string file parameters pointing to .flv content.
  • Crash manifests as an out-of-bounds write via an indexing error: base address (rdi) is in-bounds but rdi + 2*rdx lands outside the mapped heap region — look for OOB write crashes in Flash/Chrome renderer processes involving 16-bit (word) writes to heap memory.
  • Vulnerability class is heap-based buffer overflow in Adobe Flash Player triggered when loading a crafted FLV file; affects Flash before 13.0.0.302 / 18.0.0.203 (Win/OSX) and before 11.2.202.481 (Linux).
  • Intermittent crash — may require multiple page loads/refreshes to trigger; consider monitoring for repeated Flash plugin crashes or renderer restarts as a behavioral signal.
  • ·The PoC URL uses localhost for reproduction; in real-world exploitation the SWF and FLV would be hosted on an attacker-controlled server — the localhost indicator is not a network IOC.
  • ·CVE-2015-5118 is grouped with CVE-2015-3135 and CVE-2015-4432 as distinct but related heap-buffer-overflow vulnerabilities in the same Flash/AIR release; patching requires updating to Flash ≥13.0.0.302 / ≥18.0.0.203 (Win/OSX), ≥11.2.202.481 (Linux), and AIR ≥18.0.0.180.
