Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds read (CVE-ID: CVE-2019-7146)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 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/E:P/U:Clear


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.
