Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists in the dwarf2.c source code file due to the improper processing of crafted Executable and Linkable Format (ELF) files that contain a corrupted DWARF FORM block. A remote attacker can send a specially crafted ELF file, trick the victim into opening it, trigger integer overflow or underflow and cause the service to crash.

Mitigation

Install update from vendor's website.
