OpenOffice.org and StarOffice/Office Suite WMF and EMF buffer overflow

openoffice-wmf-emf-bo (31257) The risk level is classified as HighHigh Risk

Description:

OpenOffice.org and StarOffice/Office Suite are vulnerable to multiple heap-based buffer overflows, caused by improper bounds checking of META_ESCAPE, EMR_POLYPOLYGON, and EMR_POLYPOLYGON16 records in WMF and EMF files. By creating a specially-crafted WMF or EMF file and persuading a victim to open the file, a remote attacker could overflow a buffer and execute arbitrary code on the system with the privileges of the victim.
