Description
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the parse_die function that is defined in the dwarf1.c source code file due to the improper processing of crafted Executable and Linkable Format (ELF) files that contain corrupted dwarf1 debug information. A remote attacker can send a specially crafted ELF file, trick the victim into opening it, trigger integer overflow and cause the service to crash.
