GNU tar 1.16 GNU tar 1.15.1 |
Description |
|
|
Se ha descubierto una vulnerabilidad en GNU tar 1.6 y 1.15.1. La vulnerabilidad reside en un error al manejar incorrectamente el campo GNUTYPE_NAMES en la función "extract_archive()" en el archivo extract.c y la función "extract_mangle()" en mangle.c. Un atacante remoto podría sobrescribir archivos arbitrarios mediante un archivo tar que contenga GNUTYPE_NAMES con enlaces simbólicos. Existe una prueba de concepto disponible. |
