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 •
