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

Update the affected packages.
media-libs/leptonica to version: 1.81.0

Vulnerable software versions

Gentoo Linux: All versions

media-libs/leptonica: before 1.81.0

CPE2.3 External links

http://security.gentoo.org/glsa/202312-01


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) Stack-based buffer overflow

EUVDB-ID: #VU11175

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.

The weakness exists in the pixHtmlViewer function due to buffer overflow. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Update the affected packages.
media-libs/leptonica to version: 1.81.0

Vulnerable software versions

Gentoo Linux: All versions

media-libs/leptonica: before 1.81.0

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

4) Command injection

EUVDB-ID: #VU11188

Risk: High

CVSSv3.1: 8.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

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

Update the affected packages.
media-libs/leptonica to version: 1.81.0

Vulnerable software versions

Gentoo Linux: All versions

media-libs/leptonica: before 1.81.0

Is there known malware, which exploits this vulnerability?

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

5) Race condition

EUVDB-ID: #VU11225

Risk: Low

CVSSv3.1: 4.4 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N/E:U/RL:O/RC:U]

CVE-ID: CVE-2018-7441

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

Exploit availability: No

Description

The vulnerability allows a local attacker to overwrite arbitrary files on the target system.
