Security Bulletin
This security bulletin contains information about 6 vulnerabilities.
EUVDB-ID: #VU2829
Risk: High
CVSSv3.1: 8.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2011-2426
CWE-ID:
CWE-121 - Stack-based buffer overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to stack-based buffer overflow in the ActionScript Virtual Machine (AVM) component. A remote attacker can create a specially crafted Web page, trick the victim into visiting it, trigger memory corruption, and execute arbitrary code on the system with privileges of the current user.
Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.

EUVDB-ID: #VU2828
Risk: Medium
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:F/RL:O/RC:C]
CVE-ID: CVE-2011-2444
CWE-ID:
CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-input passed via a crafted URL. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user’s browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
