Adobe Flash Player is prone to multiple vulnerabilities. These vulnerabilities are as follows:
Multiple memory corruption vulnerabilities that could lead to remote code execution (CVE-2015-0347, CVE-2015-0350, CVE-2015-0352, CVE-2015-0353, CVE-2015-0354, CVE-2015-0355, CVE-2015-0360, CVE-2015-3038, CVE-2015-3041, CVE-2015-3042, CVE-2015-3043).
Type confusion vulnerability that could lead to remote code execution (CVE-2015-0356).
Buffer overflow vulnerability that could lead to remote code execution (CVE-2015-0348).
Use-after-free vulnerabilities that could lead to remote code execution (CVE-2015-0349, CVE-2015-0351, CVE-2015-0358, CVE-2015-3039).
Double-free vulnerabilities that could lead to remote code execution (CVE-2015-0346, CVE-2015-0359).
Memory leak vulnerabilities that could be used to bypass Address Space Layout Randomization (ASLR) (CVE-2015-0357, CVE-2015-3040).
Security bypass vulnerability that could lead to information disclosure (CVE-2015-3044).
Successful exploitation of these vulnerabilities could result in the attacker gaining the same rights 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 rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
Install the updates provided by Adobe immediately after appropriate testing.
Remind users not to visit untrusted websites or follow links provided by unknown or untrusted sources.
