Descriptions

The glob function in glob.c in the GNU C Library (aka glibc or libc6) before 2.27, when invoked with GLOB_TILDE, could skip freeing allocated memory when processing the ~ operator with a long user name, potentially leading to a denial of service (memory leak).

La función glob en glob.c en la biblioteca GNU C (también llamada glibc o libc6) en versiones anteriores a la 2.27, cuando se invoca con GLOB_TILDE, podría omitir la liberación de memoria asignada cuando procesa el operador ~ con un nombre de usuario largo, conduciendo potencialmente a una denegación de servicio (fuga de memoria).
