OpenSUSE Linux update for openssl-1_1

1) Cryptographic issues

EUVDB-ID: #VU21043

Risk: Low

CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-1547

CWE-ID: CWE-310 - Cryptographic Issues

Exploit availability: No

Description

The vulnerability allows a remote attacker to decrypt traffic.

The vulnerability exists due to insufficient enforcement of side channel resistant code paths. A remote attacker with ability to create a large number of signatures, where explicit parameters with no co-factor is present, can force the application to fall back to non-side channel resistant code pathsduring ECDSA signature operation and perform full key recovery.

Successful exploitation of the vulnerability may allow an attacker to decrypt communication between server and client.

Mitigation

Update the affected packages.

2) Cross-site scripting

EUVDB-ID: #VU20422

Risk: Low

CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-15476

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data when processing a checkbox value. 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.

Mitigation

Update the affected packages.

3) Unprotected storage of credentials

EUVDB-ID: #VU21237

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-15635

CWE-ID: CWE-256 - Unprotected Storage of Credentials

Exploit availability: No

Description

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to an error in encrypt-datasource-passwords data migration command that failed to encrypt user credentials for various data sources. A local user can view migration settings and reveal database credentials.

Note, this vulnerability can be exploited via Grafana web UI by pressing the "Save and test" button within a data source's settings menu.

Mitigation

Update the affected packages.

4) Padding oracle attack

EUVDB-ID: #VU21045

Risk: Low

CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-1563

CWE-ID: CWE-310 - Cryptographic Issues

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform padding oracle attack.

The vulnerability exists due to possibility to perform a Bleichenbacher padding oracle attack against the RSA key, in situations where an attacker receives automated notification of the success or failure of a decryption attempt an attacker. A remote attacker can send a very large number of messages to be decrypted, can recover a CMS/PKCS7 transported encryption key or decrypt any RSA encrypted message that was encrypted with the public RSA key.

Mitigation

Update the affected packages.

5) Input validation error

EUVDB-ID: #VU20962

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-15639

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input in the "main/translate.c". A remote attacker can send a specific RTP packet during a call and cause a crash in a specific scenario.

Mitigation

Update the affected packages.
