Description

This security bulletin contains information about 14 secuirty vulnerabilities.

1) Security bypass (CVE-ID: CVE-2014-4140)

The vulnerabiity allows a remote attacker to bypass security restrictions on the target system.

The weakness exists due to failure to use Address Space Layout Randomization (ASLR). A remote attacker can create a specially crafted Web site, trick the victim into visiting it and bypass ASLR security mechanism.

2) Memory corruption (CVE-ID: CVE-2014-4141)

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

The weakness exists due to boundary error. 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) Memory corruption (CVE-ID: CVE-2014-4138)

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

The weakness exists due to boundary error. 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.

4) Memory corruption (CVE-ID: CVE-2014-4137)

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

The weakness exists due to boundary error. 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) Memory corruption (CVE-ID: CVE-2014-4134)

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

The weakness exists due to boundary error. 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.

6) Memory corruption (CVE-ID: CVE-2014-4133)

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

The weakness exists due to boundary error. 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.

7) Memory corruption (CVE-ID: CVE-2014-4132)

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

The weakness exists due to boundary error. 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.

8) Memory corruption (CVE-ID: CVE-2014-4130)

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

The weakness exists due to boundary error. 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.

9) Memory corruption (CVE-ID: CVE-2014-4129)

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

The weakness exists due to boundary error. 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.

10) Memory corruption (CVE-ID: CVE-2014-4128)

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

The weakness exists due to boundary error. 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.

11) Memory corruption (CVE-ID: CVE-2014-4127)

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

The weakness exists due to boundary error. 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.

12) Memory corruption (CVE-ID: CVE-2014-4126)

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

The weakness exists due to boundary error. 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.

13) Privilege escalation (CVE-ID: CVE-2014-4124)

The vulnerability allows a remote attacker to obtain elevated privileges on the target system.

The weakness exists due to the failure to properly validate permissions. A remote attacker can gain elevated privileges and execute arbitrary code on the affected system.

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

14) Privilege escalation (CVE-ID: CVE-2014-4123)

The vulnerability allows a remote attacker to obtain elevated privileges on the target system.

The weakness exists due to the failure to properly validate permissions. A remote attacker can gain elevated privileges and execute arbitrary code on the affected system.

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

Note: the vulnerability was being actively exploited.
