Security Bulletin

This security bulletin contains information about 9 vulnerabilities.

1) Path traversal

EUVDB-ID: #VU23554

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2019-1348

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when the export-marks option of git fast-import is exposed also via the in-stream command feature. A remote attacker can send a specially crafted HTTP request and overwrite arbitrary paths on the system.

Mitigation

Update the affected packages.
dev-libs/libgit2 to version: 0.28.4

Can this vulnerability be exploited remotely?

Is there known malware, which exploits this vulnerability?

2) Buffer overflow

EUVDB-ID: #VU21083

Risk: High

CVSSv3.1:

CVE-ID: CVE-2019-13484

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error in the status-log viewer CGI because of   expansion in the "appfeed.c". A remote attacker can trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Update the affected packages.

3) Stack-based buffer overflow

EUVDB-ID: #VU21082

Risk: High

CVSSv3.1:

CVE-ID: CVE-2019-13486

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to access or modify data, or cause a denial of service (DoS) condition on an affected system.

The vulnerability exists in the status-log viewer component due to a boundary error in the "svcstatus.c" file because the software does not properly validate user-supplied input. A remote unauthenticated attacker can submit malicious input, trigger stack-based buffer overflow and access or modify data, or cause a DoS condition on the affected system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

4) Stack-based buffer overflow

EUVDB-ID: #VU21060

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2019-13485

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

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error when processing a long hostname or service parameter in history.c within the in the history viewer component. A remote authenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

5) Input validation error

EUVDB-ID: #VU23493

Risk: High

CVSSv3.1:

CVE-ID: CVE-2019-1350

CWE-ID: CWE-20 - Improper Input Validation

Exploit availability: No

Description

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

The vulnerability exists due to insufficient validation of user-supplied input within the Git for Visual Studio. A remote attacker can convince the user to clone a malicious repo and execute arbitrary code on the target system.

Mitigation

Update the affected packages.

6) Inclusion of Sensitive Information in Log Files

EUVDB-ID: #VU19390

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2019-13509

CWE-ID: CWE-532 - Information Exposure Through Log Files

Exploit availability: No

Description

The vulnerability allows a local attacker to access sensitive information on a targeted system.

The vulnerability exists due to the software can add secrets to the debug log when the "docker stack deploy" command is used while running in debug mode to redeploy a stack which includes non-external secrets. A local authenticated attacker can gain access to sensitive information, such as secrets in the log files on a targeted system.

Mitigation

7) Stored cross-site scripting

EUVDB-ID: #VU19241

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2019-13505

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks via the E-mail field.

The vulnerability exists due to insufficient sanitization of user-supplied data in a booking form. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

CVE-ID: CVE-2019-13504

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause a denial of service (DoS) condition on a targeted system.

The vulnerability exists due to an out-of-bounds read error in the "Exiv2::MrwImage::readMetadata" function in the "mrwimage.cpp" file. A remote attacker can create a specially crafted media file, trick the victim into opening it and cause the affected application to crash.
