Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Spoofing attack

EUVDB-ID: #VU15560

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-2018-18541

CWE-ID: CWE-451 - User Interface (UI) Misrepresentation of Critical Information (Clickjacking, spoofing)

Exploit availability: No

Description

The vulnerability allows a remote attacker to conduct IP spoofing attack.

The vulnerability exists due to connection packets can be forged when there was no challenge-response involved in the connection build up. A remote attacker can send connection packets from a spoofed IP address and occupy all server slots, or even use them for a reflection attack using map download packets.

Mitigation

Update the affected packages.

Vulnerable software versions

SUSE Linux: 15

https://lists.opensuse.org/opensuse-security-announce/2019-08/msg00077.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) Integer overflow

EUVDB-ID: #VU20391

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2019-10877

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

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

The vulnerability exists due to the multiplication of width and height were mishandled in the "CMap::Load()" in the "engine/shared/map.cpp". A remote attacker can trigger buffer overflow 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) Out-of-bounds write

EUVDB-ID: #VU20392

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2019-10878

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input in the "CDataFileReader::GetData()" and "CDataFileReader::ReplaceData()" and related functions in engine/shared/datafile.cpp. A remote attacker can trigger out-of-bounds pointer write and execute arbitrary code on the target system.

Mitigation

Update the affected packages.

4) Integer overflow

EUVDB-ID: #VU20393

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2019-10879

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

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

The vulnerability exists due to the size-related multiplications were mishandled in the "CDataFileReader::Open()" in "engine/shared/datafile.cpp". A remote attacker can trigger integer overflow 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.
