The r_read_* functions in libr/include/r_endian.h in radare2 1.2.1 allow remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted binary file, as demonstrated by the r_read_le32 function.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
