CVE-2012-1148 – expat: Memory leak in poolGrow
https://notcve.org/view.php?id=CVE-2012-1148
Memory leak in the poolGrow function in expat/lib/xmlparse.c in expat before 2.1.0 allows context-dependent attackers to cause a denial of service (memory consumption) via a large number of crafted XML files that cause improperly-handled reallocation failures when expanding entities. Múltiples fugas de memoria en la función poolGrow en expat/lib/xmlparse.c en expat anteriores a v2.1.0 podría permitir a atacantes remotos provocar una denegación de servicio (consumo de memoria) a través de un número largo de ficheros XML manipulados que provocan fallos en la relocalización cuando se expanden las entidades. A memory leak flaw was found in Expat. If an XML file processed by an application linked against Expat triggered a memory re-allocation failure, Expat failed to free the previously allocated memory. This could cause the application to exit unexpectedly or crash when all available memory is exhausted. • http://expat.cvs.sourceforge.net/viewvc/expat/expat/lib/xmlparse.c?r1=1.166&r2=1.167 http://lists.apple.com/archives/security-announce/2015/Dec/msg00005.html http://rhn.redhat.com/errata/RHSA-2012-0731.html http://rhn.redhat.com/errata/RHSA-2016-0062.html http://rhn.redhat.com/errata/RHSA-2016-2957.html http://secunia.com/advisories/49504 http://secunia.com/advisories/51024 http://secunia.com/advisories/51040 http://sourceforge.net/projects/expat/files/expat/2.1. • CWE-399: Resource Management Errors CWE-401: Missing Release of Memory after Effective Lifetime •
CVE-2009-3560 – expat: buffer over-read and crash in big2_toUtf8() on XML with malformed UTF-8 sequences
https://notcve.org/view.php?id=CVE-2009-3560
The big2_toUtf8 function in lib/xmltok.c in libexpat in Expat 2.0.1, as used in the XML-Twig module for Perl, allows context-dependent attackers to cause a denial of service (application crash) via an XML document with malformed UTF-8 sequences that trigger a buffer over-read, related to the doProlog function in lib/xmlparse.c, a different vulnerability than CVE-2009-2625 and CVE-2009-3720. La función big2_toUt8 en lib/xmltok.c en libexpat de Expat v2.0.1, como el usado en el módulo XML-Twig para Perl, permite a los atacantes dependientes del contexto provocar una denegación de servicio (caída de aplicación) mediante un documento XML con secuencias UTF-8 malformadas que disparan un desbordamiento de lectura de búfer, relacionado con la función doProlog en lib/xmlparse.c, siendo una vulnerabilidad diferente a CVE-2009-2625 y CVE-2009-3720. • http://expat.cvs.sourceforge.net/viewvc/expat/expat/lib/xmlparse.c?r1=1.164&r2=1.165 http://expat.cvs.sourceforge.net/viewvc/expat/expat/lib/xmlparse.c?view=log#rev1.165 http://lists.opensuse.org/opensuse-security-announce/2010-01/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2010-05/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2010-05/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2010-06/msg00001.html http://lists.opensuse. • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2009-3720 – expat: buffer over-read and crash on XML with malformed UTF-8 sequences
https://notcve.org/view.php?id=CVE-2009-3720
The updatePosition function in lib/xmltok_impl.c in libexpat in Expat 2.0.1, as used in Python, PyXML, w3c-libwww, and other software, allows context-dependent attackers to cause a denial of service (application crash) via an XML document with crafted UTF-8 sequences that trigger a buffer over-read, a different vulnerability than CVE-2009-2625. La función updatePosition en lib/xmltok_impl.c en libexpat en Expat v2.0.1, usado en Python, PyXML, w3c-libwww, ay otros programas, permite a atacantes dependientes de contexto, provocar una denegación de servicio (caída de aplicación) a través de un documento XML con una secuencia de caracteres UTF-8 manipulada que provoca un desbordamiento de búfer fuera de límite (over-read). Vulnerabilidad distinta de CVE-2009-2625. • http://expat.cvs.sourceforge.net/viewvc/expat/expat/lib/xmltok_impl.c?r1=1.13&r2=1.15&view=patch http://expat.cvs.sourceforge.net/viewvc/expat/expat/lib/xmltok_impl.c?view=log http://lists.fedoraproject.org/pipermail/package-announce/2010-November/051228.html http://lists.fedoraproject.org/pipermail/package-announce/2010-November/051247.html http://lists.fedoraproject.org/pipermail/package-announce/2010-November/051367.html http://lists.fedoraproject.org/pipermail/package-announce/2010-November/051405. •
