EUVDB-ID: #VU13239

Risk: Low

CVSSv3.1: 5.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2017-7608

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

Exploit availability: No

Description

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

The vulnerability exists in the ebl_object_note_type_name function of elfutils due to heap-based buffer overflow when handling Executable and Linkable Format (ELF) files by the ebl_object_note_type_namefunction, as defined in the eblobjnotetypename.c source code file. A remote attacker can trick the victim into opening an Executable and Linkable Format (ELF) file that submits malicious input, trigger memory corruption and cause the application to crash.
