LibreOffice 3.5.x before 3.5.7.2 and 3.6.x before 3.6.1, and OpenOffice.org (OOo), allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted (1) odt file to vcllo.dll, (2) ODG (Drawing document) file to svxcorelo.dll, (3) PolyPolygon record in a .wmf (Window Meta File) file embedded in a ppt (PowerPoint) file to tllo.dll, or (4) xls (Excel) file to scfiltlo.dll.
An integer overflow flaw, leading to buffer overflow, was found in the way OpenOffice.org processed invalid Escher graphics records length in PowerPoint documents. An attacker could provide a specially-crafted PowerPoint document that, when opened, would cause OpenOffice.org to crash or, potentially, execute arbitrary code with the privileges of the user running OpenOffice.org.
