Security issues were identified and fixed in libreoffice: An integer overflow vulnerability in the libreoffice graphic loading code could allow a remote attacker to cause a denial of service or potentially execute arbitrary code . An integer overflow flaw, leading to buffer overflow, was found in the way libreoffice processed invalid Escher graphics records length in PowerPoint documents. An attacker could provide a specially-crafted PowerPoint document that, when opened, would cause libreoffice to crash or, potentially, execute arbitrary code with the privileges of the user running libreoffice . libreoffice for Mandriva Linux 2011 has been upgraded to the 3.5.4 version which is not vulnerable to these issues.
