Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2019-10879)
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.
2) Out-of-bounds write (CVE-ID: CVE-2019-10878)
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.
3) Integer overflow (CVE-ID: CVE-2019-10877)
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.
