OpenOffice.org vclmi.dll buffer overflow
|openoffice-vclmi-bo (75692)||High Risk|
OpenOffice.org is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the vclmi.dll module. By persuading a victim to open a specially-crafted JPEG object within a DOC file, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
Note: This vulnerability also affects LibreOffice.
Upgrade to the latest version of OpenOffice.org (3.4 or later), available from the OpenOffice.org Web site. See References.
For other distributions:
Apply the appropriate update for your system. See References.
