Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Spoofing attack
EUVDB-ID: #VU15560
Risk: Low
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2018-18541
CWE-ID:
CWE-451 - User Interface (UI) Misrepresentation of Critical Information (Clickjacking, spoofing)
Exploit availability: No
DescriptionThe 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.
MitigationUpdate the affected packages.

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
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-2019-10877
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe 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.
MitigationUpdate the affected packages.

3) Out-of-bounds write
EUVDB-ID: #VU20392
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-2019-10878
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe 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.
MitigationUpdate the affected packages.

4) Integer overflow
EUVDB-ID: #VU20393
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-2019-10879
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe 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.
MitigationUpdate the affected packages.
