Detailed vulnerability description
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the assign_file_positions_for_non_load_sections function due to the improper processing of crafted Executable and Linkable Format (ELF) files that contain a RELRO segment that lacks a matching LOAD segment. A remote attacker can send a specially crafted ELF file, trick the victim into opening it, trigger NULL pointer dereference and cause the service to crash.
