Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Information disclosure

EUVDB-ID: #VU5449

Risk: Low

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

CVE-ID: CVE-2016-8745

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists to error within the send file code for the NIO HTTP connector, which causes current Processor object being added to the Processor cache multiple times. This behavior means that sharing the same Processor for concurrent requests can lead to leakage of potentially sensitive information between requests, such as session ID, request body, etc.

Successful exploitation of the vulnerability may allow an attacker to obtain potentially sensitive information.

Mitigation

Update the affected package to version tomcat-8.0.43-10.19.1.

Vulnerable software versions

SUSE Linux: 12

CPE2.3 External links

https://lists.opensuse.org/opensuse-security-announce/2017-05/msg00060.html


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) Information disclosure

EUVDB-ID: #VU6674

Risk: Low

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

CVE-ID: CVE-2017-5647

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists in the handling of the pipelined requests when send file was used resulted in the pipelined request being lost when send file processing of the previous request completed. A remote attacker can cause responses to appear to be sent for the wrong request.

Mitigation

Update the affected package to version tomcat-8.0.43-10.19.1.

Vulnerable software versions

SUSE Linux: 12

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

3) Security restrictions bypass

EUVDB-ID: #VU6675

Risk: Low

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

CVE-ID: CVE-2017-5648

CWE-ID: CWE-284 - Improper Access Control

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass security restrictions on the target system.

The weakness exists due to the failure to use the appropriate facade object by certain application listener calls. A remote attacker can access and modify arbitrary data.

Mitigation

Update the affected package to version tomcat-8.0.43-10.19.1.
