Descriptions
The overflow protection in Expat is removed by compilers with certain optimization settings, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted XML data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1283 and CVE-2015-2716.
La protección de desbordamiento en Expat es eliminada por los compiladores con ciertos ajustes de optimización, lo que permite a atacantes remotos provocar una denegación de servicio (caída) o posiblemente ejecutar código arbitrario a través de datos XML manipulados. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2015-1283 y CVE-2015-2716.
It was discovered that the Expat code in XML-RPC for C and C++ unexpectedly called srand in certain circumstances. This could reduce the security of calling applications. It was discovered that the Expat code in XML-RPC for C and C++ incorrectly handled seeding the random number generator. A remote attacker could possibly use this issue to cause a denial of service. Gustavo Grieco discovered that the Expat code in XML-RPC for C and C++ incorrectly handled malformed XML data. If a user or application linked against XML-RPC for C and C++ were tricked into opening a crafted XML file, an attacker could cause a denial of service, or possibly execute arbitrary code. Various other issues were also addressed.
