Security Bulletin

This security bulletin contains information about 8 vulnerabilities.

1) Type Confusion

EUVDB-ID: #VU3044

Risk: Critical

CVSSv4.0: 8.6 [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]

CVE-ID: CVE-2012-0779

CWE-ID: CWE-843 - Type confusion

Exploit availability: Yes

Description

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

The weakness exists due to object type confusion error when processing .swf files. A remote attacker can create a specially crafted .swf file, trick the victim into opening 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.

Mitigation

Update the affected packages.
