Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Use of a broken or risky cryptographic algorithm

EUVDB-ID: #VU17908

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-2019-1543

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to encrypted data.

The vulnerability exists due to incorrect implementation of the ChaCha20-Poly1305 cipher. For messages, encrypted with this cipher, a reused nonce value is used that is susceptible to serious confidentiality and integrity attacks. If an application changes the default nonce length to be longer than 12 bytes and then makes a change to the leading bytes of the nonce expecting the new value to be a new unique nonce then such an application could inadvertently encrypt messages with a reused nonce.

This vulnerability does not affect internal usage of the cipher within OpenSSL. However if an application uses this cipher directly and sets a non-default nonce length to be longer than 12 bytes, it may be vulnerable.

Mitigation

Install update from vendor's website.

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) Integer overflow

EUVDB-ID: #VU16183

Risk: High

CVSSv3.1: 9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2018-18311

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.

The vulnerability exists due to integer overflow in Perl_my_setenv when processing malicious input. A remote unauthenticated attacker can supply specially crafted data, trigger heap-based buffer overflow and cause the service to crash or execute arbitrary code with elevated privileges.

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

Mitigation

Install update from vendor's website.

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. However, proof of concept for this vulnerability is available.

3) Improper input validation

EUVDB-ID: #VU27194

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-2961

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The vulnerability exists due to improper input validation within the Discovery Framework (Oracle OHS) component in Enterprise Manager Base Platform. A remote non-authenticated attacker can exploit this vulnerability to execute arbitrary code.

Mitigation

Install update from vendor's website.
