Descriptions
The rehash mechanism in Perl 5.8.2 through 5.16.x allows context-dependent attackers to cause a denial of service (memory consumption and crash) via a crafted hash key.
El mecanismo de rehash en Perl v5.8.2 a través v5.16.x permite a atacantes dependientes de contexto provocar una denegación de servicio (consumo de memoria y caída) mediante una tecla de almohadilla diseñada.
Perl is a high-level programming language commonly used for system administration utilities and web programming. A heap overflow flaw was found in Perl. If a Perl application allowed user input to control the count argument of the string repeat operator, an attacker could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. A denial of service flaw was found in the way Perl's rehashing code implementation, responsible for recalculation of hash keys and redistribution of hash content, handled certain input. If an attacker supplied specially-crafted input to be used as hash keys by a Perl application, it could cause excessive memory consumption.
