Description: 

Multiple vulnerabilities have been discovered in Adobe Acrobat and Adobe Reader, the most severe of which could allow for code execution. The vulnerabilities are as follows:

  • One type confusion vulnerability that could lead to code execution (CVE-2017-2962).

  • Seven use-after-free vulnerabilities that could lead to code execution (CVE-2017-2950, CVE-2017-2951, CVE-2017-2955, CVE-2017-2956, CVE-2017-2957, CVE-2017-2958, CVE-2017-2961).

  • Six heap buffer overflow vulnerabilities that could lead to code execution (CVE-2017-2942, CVE-2017-2945, CVE-2017-2946, CVE-2017-2949, CVE-2017-2959, CVE-2017-2966).

  • Two buffer overflow vulnerabilities that could lead to code execution (CVE-2017-2948, CVE-2017-2952).

  • Twelve memory corruption vulnerabilities that could lead to code execution (CVE-2017-2939, CVE-2017-2940, CVE-2017-2941, CVE-2017-2943, CVE-2017-2944, CVE-2017-2953, CVE-2017-2954, CVE-2017-2960, CVE-2017-2963, CVE-2017-2964, CVE-2017-2965, CVE-2017-2967).

  • One security bypass vulnerability (CVE-2017-2947).

Successful exploitation of the most severe of these vulnerabilities could result in the attacker gaining control of the affected system.

Actions: 
  • After appropriate testing, immediately install the updates provided by Adobe.

  • 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 websites or follow links provided by unknown or untrusted sources.
  • Inform and educate users regarding the threats posed by hypertext links contained in emails or attachments especially from untrusted sources.
  • Apply the Principle of Least Privilege to all systems and services.
