1) Out-of-bounds read (CVE-ID: CVE-2019-14906)

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

A remote attacker can trick a victim to open a specially crafted file and perform a denial of service attack.

Note, this issue exists due to incorrect patch implementation in Red Hat Enterprise Linux 7 for vulnerability CVE-2019-13616, described in SB2019112513.
