Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU38195

Risk: Low

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

CVE-ID: CVE-2017-14737

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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

A cryptographic cache-based side channel in the RSA implementation in Botan before 1.10.17, and 1.11.x and 2.x before 2.3.0, allows a local attacker to recover information about RSA secret keys, as demonstrated by CacheD. This occurs because an array is indexed with bits derived from a secret key.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

Fedora: 26

botan: before 1.10.17-1.fc26

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) Improper input validation

EUVDB-ID: #VU6398

Risk: Low

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2017-2801

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to disclose potentially sensitive information or cause (DoS) condition.

The vulnerability exists due to improper validation of X.509 certificate fields when processing a specially formed DN. A remote attacker can submit a crafted X.509 certificate to affected client or server software, bypass security restrictions and cause out of bound memory read.

Successful exploitation of the vulnerability may result in information disclosure or denial of service on the targeted system.

Mitigation

Install updates from vendor's repository.
