Detailed vulnerability description
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to improper bounds checking when using the swap_std_reloc_in function, as defined in the aoutx.h source code file in the Binary File Descriptor (BFD) library. A remote attacker can submit a specially crafted ELF file, trigger NULL pointer dereference and cause the service to crash.
