Descriptions
Heap-based buffer overflow in the Perl_repeatcpy function in util.c in Perl 5.12.x before 5.12.5, 5.14.x before 5.14.3, and 5.15.x before 15.15.5 allows context-dependent attackers to cause a denial of service (memory consumption and crash) or possibly execute arbitrary code via the 'x' string repeat operator.
Desbordamiento de bufer en memoria dinámica en la función Perl_repeatcpy en util.c en Perl v5.12.x antes de v5.12.5, v5.14.x antes de v5.14.3, y v5.15.x antes de v5.15.5 permite a atacantes dependientes de contexto provocar una denegación de servicio (consumo de memoria y caída) o posiblemente ejecutar código arbitrario mediante el operador 'x' string repeat.
Multiple vulnerabilities have been found in Perl and Locale::Maketext Perl module, the worst of which could allow a context-dependent attacker to execute arbitrary code. Versions less than 5.16.3 are affected.
