Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Command injection

EUVDB-ID: #VU11188

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2018-7440

CWE-ID: CWE-77 - Command injection

Exploit availability: No

Description

The vulnerability allows a remote unauthenticated attacker to execute arbitrary code on the target system.

The weakness exists in the gplotMakeOutput function due to insufficient validation of commands used in the gplot rootname argument. A remote attacker can execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

Fedora: 28

leptonica: before 1.76.0-1.fc28

CPE2.3 External links

https://bodhi.fedoraproject.org/updates/FEDORA-2018-c6e8b5f529


Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Command injection

EUVDB-ID: #VU10359

Risk: Low

CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-3836

CWE-ID: CWE-77 - Command injection

Exploit availability: No

Description

The vulnerability allows a remote attacker to inject arbitrary commands.

The weakness exists in the gplotMakeOutput function due to insufficient validation of user-supplied input. A local attacker can submit a specially crafted gplot rootname argument, inject arbitrary commands and execute arbitrary code with system or root privileges.

Successful exploitation of the vulnerabiiity may result in system compromise.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

Fedora: 28

leptonica: before 1.76.0-1.fc28

https://bodhi.fedoraproject.org/updates/FEDORA-2018-c6e8b5f529


Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

3) Path traversal

EUVDB-ID: #VU11189

Risk: Low

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-7442

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Exploit availability: No

Description

The vulnerability allows a remote unauthenticated attacker to conduct path traversal attack on the target system.

The weakness exists in the gplotMakeOutput function due to insufficient validation of characters used in the gplot rootname argument. A remote attacker can trigger path traversal and gain access to potentially sensitive information.

Mitigation

Install updates from vendor's repository.
