Multiple Vulnerabilities in Adobe Flash Player Could Allow Remote Code Execution (APSB15-09)
MS-ISAC ADVISORY NUMBER:2015-054
Multiple vulnerabilities have been discovered in Adobe Flash Player. 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 of thesevulnerabilitiescould result in an attacker compromising data security, potentially allowing access to confidential data, or could compromise processing resources in a user's computer.
There are currently no reports of these vulnerabilities being exploited in the wild.

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-2015-3078, CVE-2015-3089, CVE-2015-3090, CVE-2015-3093).
Heap overflow vulnerability that could lead to remote code execution (CVE-2015-3088).
Time-of-check time-of-use (TOCTOU) race condition that could be exploited to bypass Protected Mode in Internet Explorer (CVE-2015-3081).
Integer overflow vulnerability that could lead to remote code execution (CVE-2015-3087).
Type confusion vulnerabilities that could lead to remote code execution (CVE-2015-3077, CVE-2015-3084, CVE-2015-3086).
Use-after-free vulnerability that could lead to remote code execution (CVE-2015-3080).
Memory leak vulnerabilities that could be used to bypass Address Space Layout Randomization (ASLR) (CVE-2015-3091, CVE-2015-3092).
Security bypass vulnerabilities that could be exploited to write arbitrary data to the file system under user permissions (CVE-2015-3082, CVE-2015-3083, CVE-2015-3085).
Security bypass vulnerability that could lead to information disclosure (CVE-2015-3079), and provide additional hardening to protect against 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.
We recommend the following actions be taken:
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.
Do not open email attachments from unknown or untrusted sources.
Limit user account privileges to those required only.
