CVE-ID: CVE-2014-0172

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in Integer overflow in the check_section function in dwarf_begin_elf.c in the libdw library, as used in elfutils 0.153 and possibly through 0.158. A remote attacker can use a malformed compressed debug section in an ELF file to trigger heap-based buffer overflow and execute arbitrary code on the target system.
