1) Improper validation of array index
EUVDB-ID: #VU1392
Risk: Critical
CVSSv4.0: 8.4 [CVSS:4.0/AV:L/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-2009-3953
CWE-ID:
CWE-129 - Improper Validation of Array Index
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to array indexing error in U3D support. A remote attacker can create a specially crafted .pdf file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.
Note: this vulnerability is being actively exploited.
