Descriptions

The WPXContentListener::_closeTableRow function in WPXContentListener.cpp in libwpd 0.8.8, as used by OpenOffice.org (OOo) before 3.4, allows remote attackers to execute arbitrary code via a crafted Wordperfect .WPD document that causes a negative array index to be used. NOTE: some sources report this issue as an integer overflow.

La función WPXContentListener::_closeTableRow en WPXContentListener.cpp en libwpd v0.8.8, tal y como es usado por OpenOffice.org (OOo) antes de v3.4, permite a atacantes remotos ejecutar código de su elección a través de un documento WordPerfect .WPD debidamente modificado, que provoca que se use un índice de matriz negativa. NOTA: algunas fuentes informan de este tema como un desbordamiento de enteros.

Multiple vulnerabilities have been found in OpenOffice and LibreOffice, the worst of which may result in execution of arbitrary code.
