Descriptions

Multiple integer overflows in the (1) get_time_t_max and (2) get_time_t_min functions in archive_read_support_format_mtree.c in libarchive before 3.2.0 allow remote attackers to have unspecified impact via a crafted mtree file, which triggers undefined behavior.

MĂșltiples desbordamientos de entero en las funciones (1) get_time_t_max y (2) get_time_t_min en archive_read_support_format_mtree.c en libarchive en versiones anteriores a 3.2.0 permiten a atacantes remotos tener impacto no especificado a travĂ©s de un archivo mtree manipulado, lo que desencadena un comportamiento no definido.

Undefined behavior (signed integer overflow) was discovered in libarchive, in the MTREE parser's calculation of maximum and minimum dates. A crafted mtree file could potentially cause denial of service.
