CVE-2015-3113Exploited in the wildNVD status: Analyzed

Adobe Flash Player Heap-Based Buffer Overflow

Published Updated By the CyberSecBulletin desk

CVE-2015-3113 is a critical-severity out-of-bounds write vulnerability in Flash Player from Adobe, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 13.0.0.296, 18.0.0.194, 11.2.202.468 as the first without the flaw, so updating Flash Player to one of those releases or later removes the exposure. CISA added it to the Known Exploited Vulnerabilities catalogue on April 13, 2022, which means attacks have been observed in the wild.

Patch now

Attackers are already exploiting this vulnerability, according to CISA.

What to do

  1. Update Flash Player to 13.0.0.296 or 18.0.0.194 or 11.2.202.468, whichever matches your release line, or a later version.
  2. Update Insight Orchestration to 7.5.0 or a later version.
  3. Update System Management Homepage to 7.5.0 or a later version.
  4. CISA's required action: The impacted product is end-of-life and should be disconnected if still in use.
  5. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Heap-based buffer overflow in Adobe Flash Player before 13.0.0.296 and 14.x through 18.x before 18.0.0.194 on Windows and OS X and before 11.2.202.468 on Linux allows remote attackers to execute arbitrary code via unspecified vectors, as exploited in the wild in June 2015.

The underlying weakness: Out-of-bounds Write

The product writes data past the end, or before the beginning, of the intended buffer.

How developers prevent this class of flaw

  • Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, many languages that perform their own memory management, such as Java and Perl, are not subject to buffer overflows. Other languages, such as Ada and C#, typically provide overflow protection, but the protection can be disabled by the programmer. Be wary that a language's interface to native code may still be subject to overflows, even if the language itself is theoretically safe.
  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. Examples include the Safe C String Library (SafeStr) by Messier and Viega, and the Strsafe.h library from Microsoft. These libraries provide safer versions of overflow-prone string-handling functions.
  • Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index checking. D3-SFCV (Stack Frame Canary Validation) from D3FEND discusses canary-based detection in detail.
