Integer Overflow RCE in Adobe Flash Player and Adobe AIR

IdentifiersCVE-2015-8651CWE-190· Integer Overflow or Wraparound

CVE-2015-8651 is an integer overflow vulnerability in Adobe Flash Player and Adobe AIR. According to the provided content, affected products include Adobe Flash Player before 18.0.0.324 and 19.x/20.x before 20.0.0.267 on Windows and OS X, Flash Player before 11.2.202.559 on Linux, Adobe AIR before 20.0.0.233, Adobe AIR SDK before 20.0.0.233, and Adobe AIR SDK & Compiler before 20.0.0.233. Successful exploitation allows arbitrary code execution via unspecified vectors. The supporting context also indicates the flaw was used in exploit-kit-driven attacks, where a Flash object selected this exploit based on the victim's installed Flash version.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation results in arbitrary code execution in the context of the targeted application/user. In observed campaigns referenced in the content, exploitation of CVE-2015-8651 was used as an execution primitive within malvertising and exploit-kit chains, enabling delivery and execution of follow-on malware payloads including trojan downloaders and banking malware.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, disable or uninstall Adobe Flash Player and Adobe AIR where feasible, restrict execution of Flash content in browsers and applications, use click-to-play or equivalent browser controls, limit exposure to untrusted web content and malvertising, and apply application control and endpoint protections to reduce post-exploitation payload execution. Network filtering and browser hardening can reduce exposure to exploit-kit delivery paths.

Remediation

Patch, then assume compromise.

Upgrade affected Adobe products to fixed versions or later. Specifically, update Adobe Flash Player to 18.0.0.324 or later for the 18.x branch, 20.0.0.267 or later for affected 19.x/20.x branches on Windows and OS X, 11.2.202.559 or later on Linux, and update Adobe AIR, Adobe AIR SDK, and Adobe AIR SDK & Compiler to 20.0.0.233 or later. Where possible, remove or fully decommission Adobe Flash Player and associated runtimes from environments that no longer require them.
