Out-of-bounds read in elfutils - CVE-2019-7146

Vulnerability identifier: #VU17327

CSH Severity: Low

CVSS v4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2019-7146

CWE-ID: CWE-125

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper handling of Executable and Linkable Format (ELF) files by the ebl_object_note function, as defined in the eblobjnote.c source code file. A remote attacker can trick the victim into opening a specially crafted ELF file that submits malicious input, trigger a buffer over-read condition and cause the affected application to crash, resulting in a DoS condition.
