| schemasystem.dll in Valve Dota 2 before 7.23f allows remote attackers to achieve code execution or denial of service by creating a gaming server and inviting a victim to this server, because a crafted map is mishandled during a GetValue call. | ||||
| CVE-2020-6019 | 1 Valvesoftware | 1 Game Networking Sockets | 2024-11-21 | 7.5 High |
| Valve's Game Networking Sockets prior to version v1.2.0 improperly handles inlined statistics messages in function CConnectionTransportUDPBase::Received_Data(), leading to an exception thrown from libprotobuf and resulting in a crash. | ||||
| CVE-2020-6018 | 1 Valvesoftware | 1 Game Networking Sockets | 2024-11-21 | 9.8 Critical |
| Valve's Game Networking Sockets prior to version v1.2.0 improperly handles long encrypted messages in function AES_GCM_DecryptContext::Decrypt() when compiled using libsodium, leading to a Stack-Based Buffer Overflow and resulting in a memory corruption and possibly even a remote code execution. | ||||
| CVE-2020-6017 | 1 Valvesoftware | 1 Game Networking Sockets | 2024-11-21 | 9.8 Critical |
| Valve's Game Networking Sockets prior to version v1.2.0 improperly handles long unreliable segments in function SNP_ReceiveUnreliableSegment() when configured to support plain-text messages, leading to a Heap-Based Buffer Overflow and resulting in a memory corruption and possibly even a remote code execution. | ||||
| CVE-2020-6016 | 1 Valvesoftware | 1 Game Networking Sockets | 2024-11-21 | 9.8 Critical |
| Valve's Game Networking Sockets prior to version v1.2.0 improperly handles unreliable segments with negative offsets in function SNP_ReceiveUnreliableSegment(), leading to a Heap-Based Buffer Underflow and a free() of memory not from the heap, resulting in a memory corruption and probably even a remote code execution. | ||||
| CVE-2020-15530 | 1 Valvesoftware | 1 Steam Client | 2024-11-21 | 7.8 High |
| An issue was discovered in Valve Steam Client 2.10.91.91. The installer allows local users to gain NT AUTHORITY\SYSTEM privileges because some parts of %PROGRAMFILES(X86)%\Steam and/or %COMMONPROGRAMFILES(X86)%\Steam have weak permissions during a critical time window.
