Descriptions

Integer underflow in regcomp.c in Perl before 5.20, as used in Apple OS X before 10.10.5 and other products, allows context-dependent attackers to execute arbitrary code or cause a denial of service (application crash) via a long digit string associated with an invalid backreference within a regular expression.

Desbordamiento inferior de enteros en regcomp.c en Perl en versiones anteriores a 5.20, tal como se utiliza en Apple OS X en versiones anteriores a 10.10.5 y otros productos, permite a atacantes dependientes del contexto ejecutar código arbitrario o causar una denegación de servicio (caída de aplicación) a través de una cadena larga de dígitos asociados con una referencia inversa no válida dentro de una expresión regular.

It was discovered that Perl incorrectly handled certain regular expressions with an invalid backreference. An attacker could use this issue to cause Perl to crash, resulting in a denial of service, or possibly execute arbitrary code. Markus Vervier discovered that Perl incorrectly handled nesting in the Data::Dumper module. An attacker could use this issue to cause Perl to consume memory and crash, resulting in a denial of service. Various other issues were also addressed.
