Descriptions

Use-after-free vulnerability in the spl_ptr_heap_insert function in ext/spl/spl_heap.c in PHP before 5.5.27 and 5.6.x before 5.6.11 allows remote attackers to execute arbitrary code by triggering a failed SplMinHeap::compare operation.

Vulnerabilidad de uso después de liberación de memoria en la función spl_ptr_heap_insert en ext/spl/spl_heap.c en PHP en versiones anteriores a 5.5.27 y 5.6.x en versiones anteriores a 5.6.11 permite a atacantes remotos ejecutar código arbitrario desencadenando una operación SplMinHeap::compare fallida.

It was discovered that PHP incorrectly handled certain SplMinHeap::compare operations. A remote attacker could use this issue to cause PHP to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. Various other issues were also addressed.
