Description

This security bulletin contains information about 7 secuirty vulnerabilities.

1) Security bypass (CVE-ID: CVE-2014-0580)

The vulnerability allows a remote attacker to circumvent the Same Origin Policy on the target system.

The weakness exists due to an error in the setClipboard() function. A remote attacker can create a specially crafted shockwave file, trick the victim into into viewing it and insert persistent data into the clipboard.

Successful exploitation of the vulnerability results in security bypass on the vulnerable system.

2) Memory corruption (CVE-ID: CVE-2014-0587)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to boundary error when processing .swf files. A remote attacker can create a specially crafted Web site, trick the victim into visiting it, trigger memory corruption and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

3) Use-after-free error (CVE-ID: CVE-2014-8439)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to use-after-free error when processing .swf files. A remote attacker can create a specially crafted Web site, trick the victim into visiting it, trigger memory corruption and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

Note: the vulnerability was being actively exploited.

4) Use-after-free error (CVE-ID: CVE-2014-8443)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to use-after-free error when processing .swf files. A remote attacker can create a specially crafted Web site, trick the victim into visiting it, trigger memory corruption and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

5) Information disclosure (CVE-ID: CVE-2014-9162)

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists due to unknown error. A remote attacker can read important data on the affected system.

Successful exploitation of the vulnerability results in information disclosure on the vulnerable system.

6) Stack-based buffer overflow (CVE-ID: CVE-2014-9163)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to stack-based buffer overflow when processing .swf files. A remote attacker can create a specially crafted Web site, trick the victim into visiting it, trigger memory corruption and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

Note: the vulnerability was being actively exploited.

7) Memory corruption (CVE-ID: CVE-2014-9164)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to boundary error when processing .swf files. A remote attacker can create a specially crafted Web site, trick the victim into visiting it, trigger memory corruption and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.
