Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) 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.

Vulnerable software versions

Fedora: 29

mingw-leptonica: before 1.77.0-1.fc29

leptonica: before 1.77.0-1.fc29

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) Race condition

EUVDB-ID: #VU11225

Risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-7441

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description
