CVE-2009-2139

Hay un desbordamiento de búfer en la región heap de la memoria en svtools/source/filter.vcl/wmf/enhwmf.cxx en Go-oo versiones 2.xy 3.x anterior a 3.0.1, anteriormente ooo-build y relacionado con OpenOffice.org (OOo), permite a los atacantes remotos ejecutar código arbitrario por medio de un archivo EMF creado, un problema similar al CVE-2008-2238.

This update provides a new OpenOffice.org version 3.1.1. An integer underflow might allow remote attackers to execute arbitrary code via crafted records in the document table of a Word document, leading to a heap-based buffer overflow. A heap-based buffer overflow might allow remote attackers to execute arbitrary code via unspecified records in a crafted Word document, related to table parsing. A heap-based buffer overflow allows remote attackers to execute arbitrary code via a crafted EMF file. Multiple heap-based buffer overflows allow remote attackers to execute arbitrary code via a crafted EMF+ file. OpenOffice's xmlsec uses a bundled Libtool which might load.la file in the current working directory allowing local users to gain privileges via a Trojan horse file. For enabling such vulnerability xmlsec has to use --enable-crypto_dl building flag however it does not, although the fix keeps protected against this threat whenever that flag had been enabled.
