Security updates available for Adobe Flash Player (APSB14-24)

ITS Advisory Number: 
2014-093
Date(s) Issued: 
Tuesday, November 11, 2014
Subject: 
Security updates available for Adobe Flash Player (APSB14-24)
Overview: 

Multiple vulnerabilities have been discovered in Adobe Flash Player that could allow remote code execution. Adobe Flash Player is a widely distributed multimedia and application player used to enhance the user experience when visiting web pages or reading email messages.

Successful exploitation could result in an attacker gaining the same privileges as the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user access.

Systems Affected: 
  • Adobe Flash Player 15.0.0.189 and earlier version
  • Adobe Flash Player 13.0.0.250 and earlier 13.x versions
  • Adobe Flash Player 11.2.202.411 and earlier versions for Linux
  • Adobe AIR desktop runtime 15.0.0.293 and earlier versions
  • Adobe AIR SDK 15.0.0.302 and earlier versions
  • Adobe AIR SDK & Compiler 15.0.0.302 and earlier versions
  • Adobe AIR 15.0.0.293 and earlier versions for Android

Description: 

Adobe Flash Player is prone to multiple vulnerabilities that could allow for remote code execution. These vulnerabilities are as follows:

  • These updates resolve use-after-free vulnerabilities that could lead to code execution (CVE-2014-0573, CVE-2014-0588, CVE-2014-8438).
  • These updates resolve a double free vulnerability that could lead to code execution (CVE-2014-0574).
  • These updates resolve type confusion vulnerabilities that could lead to code execution (CVE-2014-0577, CVE-2014-0584, CVE-2014-0585, CVE-2014-0586, CVE-2014-0590).
  • These updates resolve heap buffer overflow vulnerabilities that could lead to code execution (CVE-2014-0582, CVE-2014-0589).
  • These updates resolve an information disclosure vulnerability that could be exploited to disclose session tokens (CVE-2014-8437).
  • These updates resolve a heap buffer overflow vulnerability that could be exploited to perform privilege escalation from low to medium integrity level (CVE-2014-0583). 
  • These updates resolve a permission issue that could be exploited to perform privilege escalation from low to medium integrity level (CVE-2014-8442).
Actions: 

We recommend the following actions be taken:

  • Install the updates provided by Adobe immediately after appropriate testing.
  • Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
  • Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
  • Remind users not to open email attachments from unknown users or suspicious emails from trusted sources.
