Descriptions

Integer overflow in the _gdContributionsAlloc function in gd_interpolation.c in GD Graphics Library (aka libgd) before 2.2.3 allows remote attackers to cause a denial of service (out-of-bounds memory write or memory consumption) via unspecified vectors.

Desbordamiento de entero en la función _gdContributionsAlloc en gd_interpolation.c en GD Graphics Library (también conocida como libgd) en versiones anteriores a 2.2.3 permite a atacantes remotos causar una denegación de servicio (escritura de memoria fuera de límites o consumo de memoria) a través de vectores no especificados.

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. The rh-php56 packages provide a recent stable release of PHP with PEAR 1.9.5 and enhanced language features including constant expressions, variadic functions, arguments unpacking, and the interactive debuger. The memcache, mongo, and XDebug extensions are also included. The rh-php56 Software Collection has been upgraded to version 5.6.25, which provides a number of bug fixes and enhancements over the previous version. Security Fixes in the rh-php56-php component have been added.
