Description
This security bulletin contains information about 3 vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2013-0504)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to buffer overflow, caused by improper bounds checking by the Flash Player broker service. A remote attacker can create a specially crafted Web site serving malicious Flash (SWF) content, 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.
2) Arbitrary code execution (CVE-ID: CVE-2013-0648)
CWE-ID: CWE-399 - Resource Management Errors
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Red
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to an error in the ExternalInterface ActionScript feature. A remote attacker can create specially crafted Web site serving malicious Flash (SWF) content, trick the victim into visiting it 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.
3) Arbitrary code execution (CVE-ID: CVE-2013-0643)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Red
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to an error when handling permissions of the Flash Player Firefox sandbox. A remote attacker can create specially crafted Web site serving malicious Flash (SWF) content, trick the victim into visiting it, bypass the sandbox restrictions and execute arbitrary code outside the sandbox 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.
