CVE-ID: CVE-2014-8502

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 Heap-based buffer overflow in the pe_print_edata function in bfd/peXXigen.c in GNU binutils 2.24 and earlier. A remote attacker can use a truncated export table in a PE file. to trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
