1) Stack-based buffer overflow

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

Description

The 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.

Mitigation

Update the affected packages.
