Integer overflow in the vclmi.dll module in OpenOffice.org (OOo) 3.3, 3.4 Beta, and possibly earlier, and LibreOffice before 3.5.3, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted embedded image object, as demonstrated by a JPEG image in a .DOC file, which triggers a heap-based buffer overflow.

Security readout for executives and security teams

A malicious document with an embedded image could crash vulnerable OpenOffice.org or LibreOffice installations and may allow code execution. The available sources identify OpenOffice.org 3.3, 3.4 Beta, possibly earlier, and LibreOffice before 3.5.3 as affected. Exposure is most likely on endpoints still running legacy OpenOffice.org or LibreOffice versions and opening untrusted office documents. The bundle does not identify server-side products or modern supported versions as affected. Prioritize remediation where vulnerable office suites remain in use by staff who receive external documents. The risk is older but meaningful because exploitation only requires a crafted document reaching a user. Mitigation focus: Upgrade LibreOffice installations older than 3.5.3.; Retire or update OpenOffice.org 3.3, 3.4 Beta, and possibly earlier versions.; Apply fixed packages from the relevant Linux distribution advisory..
