An integer overflow vulnerability in the IBM Lotus Symphony visual class Library module (vclmi.dll) could allow a remote attacker to cause a denial of service (application crash) or potentially execute arbitrary code on vulnerable installations of Lotus Symphony.
CVE ID: CVE-2012-0192
DESCRIPTION: Various graphic objects, such as JPEG and PNG images, can be embedded within Lotus Symphony documents. Due to an integer overflow vulnerability in the visual class library module (vclmi.dll) used by Lotus Symphony, it might be possible for a remote attacker to cause a denial of service or potentially execute arbitrary code on the system. For a remote attacker to exploit this vulnerability, the following steps must be accomplished:
- The attacker needs to create a malicious document file containing a specially-crafted embedded graphic object, and host that file on a web site or send it to potential users as an email attachment.
- User must be persuaded to open the malicious document in vulnerable versions of Lotus Symphony.
