Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Memory corruption

EUVDB-ID: #VU1278

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-2009-0235

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

The weakness exists due to buffer overflow when parsing a malformed Word 97 document in Microsoft WordPad. A remote attacker can create a specially crafted Word 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.
