Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Path traversal

EUVDB-ID: #VU11187

Risk: Low

CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2017-18196

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

Exploit availability: No

Description

The vulnerability allows a local attacker to obtain potentially sensitive information on the target system.

The weakness exists due to improper security restrictions. A local attacker can access a directory in the /tmp directory tree and gain access to potentially sensitive information, including arbitrary files.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

Fedora: 27

mingw-leptonica: before 1.74.4-4.fc27

leptonica: before 1.74.4-5.fc27

CPE2.3 External links

https://bodhi.fedoraproject.org/updates/FEDORA-2018-cbf621a53c


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.

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.

3) Stack-based buffer overflow

EUVDB-ID: #VU11175

Risk: Low

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

CVE-ID: CVE-2018-7186

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: No

Description

The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.

The weakness exists in the gplotRead and ptaReadStream functions due to stack-based buffer overflow. A remote attacker can trigger memory corruption and cause the service to crash.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

Fedora: 27

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.

4) Buffer overflow

EUVDB-ID: #VU11176

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-2018-7247

CWE-ID: CWE-120 - Buffer overflow

Exploit availability: No

Description

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