CVE-2016-5237 1 Valvesoftware 1 Steamos 2025-04-20 1.9 LOW 4.8 MEDIUM
Valve Steam 3.42.16.13 uses weak permissions for the files in the Steam program directory, which allows local users to modify the files and possibly gain privileges as demonstrated by a Trojan horse Steam.exe file.
CVE-2017-17878 1 Valvesoftware 2 Steam Link, Steam Link Firmware 2025-04-20 10.0 HIGH 9.8 CRITICAL
An issue was discovered in Valve Steam Link build 643. Root passwords longer than 8 characters are truncated because of the default use of DES (aka the CONFIG_FEATURE_DEFAULT_PASSWD_ALGO="des" setting).
CVE-2017-17877 1 Valvesoftware 2 Steam Link, Steam Link Firmware 2025-04-20 10.0 HIGH 9.8 CRITICAL
An issue was discovered in Valve Steam Link build 643. When the SSH daemon is enabled for local development, the device is publicly available via IPv6 TCP port 22 over the internet (with stateless address autoconfiguration) by default, which makes it easier for remote attackers to obtain access by guessing 24 bits of the MAC address and attempting a root login. This can be exploited in conjunction with CVE-2017-17878.
CVE-2015-7985 1 Valvesoftware 1 Steam Client 2025-04-12 7.2 HIGH N/A
Valve Steam 2.10.91.91 uses weak permissions (Users: read and write) for the Install folder, which allows local users to gain privileges via a Trojan horse steam.exe file.
CVE-2015-4016 1 Valvesoftware 1 Steam Client 2025-04-12 5.0 MEDIUM N/A
The client detection protocol in Valve Steam allows remote attackers to cause a denial of service (process crash) via a crafted response to a broadcast packet.
CVE-2013-7128 1 Valvesoftware 1 Steamos 2025-04-11 2.1 LOW N/A
Valve Bug Reporter in the valve-bugreporter package 2.10+bsos1 in Valve SteamOS Beta stores cleartext credentials in a .valve-bugreporter.cfg file upon a Remember Credentials action, which allows local users to obtain sensitive information by reading this file.
CVE-2008-7203 1 Valvesoftware 1 Counter-strike 2025-04-09 5.0 MEDIUM N/A
Valve Software Half-Life Counter-Strike 1.6 allows remote attackers to cause a denial of service (crash) via multiple crafted login packets.
CVE-2023-30382 1 Valvesoftware 1 Half-life 2025-01-17 N/A 7.3 HIGH
A buffer overflow in the component hl.exe of Valve Half-Life up to 5433873 allows attackers to execute arbitrary code and escalate privileges by supplying crafted parameters.
CVE-2023-38312 1 Valvesoftware 1 Counter-strike 2024-11-21 N/A 7.5 HIGH
A directory traversal vulnerability in Valve Counter-Strike 8684 allows a client (with remote control access to a game server) to read arbitrary files from the underlying server via the motdfile console variable.
CVE-2023-35855 1 Valvesoftware 1 Counter-strike 2024-11-21 N/A 9.8 CRITICAL
A buffer overflow in Counter-Strike through 8684 allows a game server to execute arbitrary code on a remote client's machine by modifying the lservercfgfile console variable.
CVE-2021-30481 1 Valvesoftware 1 Steam Client 2024-11-21 6.0 MEDIUM 8.0 HIGH
Valve Steam through 2021-04-10, when a Source engine game is installed, allows remote authenticated users to execute arbitrary code because of a buffer overflow that occurs for a Steam invite after one click.
CVE-2020-9005 1 Valvesoftware 1 Dota 2 2024-11-21 6.8 MEDIUM 7.8 HIGH
meshsystem.dll in Valve Dota 2 through 2020-02-17 allows remote attackers to achieve code execution or denial of service by creating a gaming server with a crafted map, and inviting a victim to this server. A GetValue call is mishandled.
CVE-2020-7952 1 Valvesoftware 1 Dota 2 2024-11-21 6.8 MEDIUM 7.8 HIGH
rendersystemdx9.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 affected by memory corruption.
CVE-2020-7951 1 Valvesoftware 1 Dota 2 2024-11-21 6.8 MEDIUM 7.8 HIGH
meshsystem.dll in Valve Dota 2 before 7.23e 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 affected by memory corruption.
CVE-2020-7950 1 Valvesoftware 1 Dota 2 2024-11-21 6.8 MEDIUM 7.8 HIGH
meshsystem.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 vulnerable function call.
CVE-2020-7949 1 Valvesoftware 1 Dota 2 2024-11-21 6.8 MEDIUM 7.8 HIGH
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 5.0 MEDIUM 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.

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 7.5 HIGH 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 10.0 HIGH 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.
