Integer overflow in filter/source/msfilter/msdffimp.cxx 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 (crash) and possibly execute arbitrary code via the length of an Escher graphics record in a PowerPoint (.ppt) document, which triggers a buffer overflow.

oowriter in OpenOffice.org 3.3.0 and LibreOffice before 3.4.3 allows user-assisted remote attackers to cause a denial of service (crash) via a crafted DOC file that triggers an out-of-bounds read in the DOC sprm parser.
