CVE-2007-5745

Múltiples desbordamientos de búfer en la región heap de la memoria en OpenOffice.org versiones anteriores a 2.4, permiten a los atacantes remotos causar una denegación de servicio (bloqueo) y posiblemente ejecutar código arbitrario por medio de un archivo Quattro Pro (QPRO) con (1) Atributo y (2) registros de Descripción de Fuente diseñados.

Remote exploitation of multiple buffer overflow vulnerabilities in OpenOffice, as included in various vendors' operating system distributions, allows attackers to execute arbitrary code with the privileges of the logged in user. The first vulnerability occurs when parsing "Attribute" records from the file. Due to a lack of bounds checking during a loop that reads these records, an attacker can trigger a heap overflow by inserting more than 256 records. The second vulnerability is nearly identical to the first one, but involves the "Font Description" record instead of the "Attribute" record.
