No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
6) Out-of-bounds write
EUVDB-ID: #VU24078
Risk: Low
CVSSv3.1: 7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2019-5188
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a local user to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in the directory rehashing functionality in "rehash.c" within the "mutate_name()" function. A local user can use a specially crafted ext4 directory, trigger out-of-bounds write on the stack and execute arbitrary code on the target system.

CVE-ID: CVE-2017-12652
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

8) Permissions, Privileges, and Access Controls
EUVDB-ID: #VU18276
Risk: Medium
CVSSv3.1: 4.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-11068
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass certain security restrictions.
The vulnerability exists due to an error within the xsltCheckRead() and xsltCheckWrite() functions when processing requests from remote servers. A remote attacker can trick the victim into opening a specially crafted URL that will result in "-1 error" code but the URL itself will be processed by the application later.
Successful exploitation of the vulnerability may allow an attacker to bypass certain security restrictions and perform XXE attacks.Mitigation
