dotnet: .NET Framework: Remote Denial of Service due to uncontrolled resource allocation

A flaw was found in .NET Framework. An unauthorized attacker can exploit this vulnerability remotely by causing the system to allocate resources without proper limits or throttling. This uncontrolled resource allocation can lead to a Denial of Service DoS, making the affected system unresponsive ...

dotnet: .NET: Denial of Service due to uncontrolled resource allocation

A flaw was found in .NET where uncontrolled allocation of resources can lead to a Denial of Service DoS. An unauthorized remote attacker could exploit this vulnerability by continuously requesting resources without limits or throttling, causing the affected system to become unresponsive or crash...

dotnet: .NET: Denial of Service vulnerability due to uncontrolled resource allocation

A flaw was found in .NET where uncontrolled resource allocation can be exploited by an unauthorized attacker over a network. This vulnerability allows the attacker to exhaust available resources, leading to a Denial of Service DoS condition. The lack of limits or throttling mechanisms enables an...

.NET: .NET: Network Spoofing Vulnerability

A flaw was found in .NET. An authorized attacker can exploit this vulnerability by leveraging improper encoding or escaping of output. This allows the attacker to perform spoofing over a network, potentially deceiving users or systems into believing they are interacting with a trusted entity...

kernel: geneve: Fix use-after-free in geneve_find_dev().

A use-after-free vulnerability exists in the Linux kernel. When devnet is dismantled, the geneveexitbatchrtnl function calls unregisternetdevicequeue for each device in the network namespace. Later, when the device is freed, it is still linked to the backend UDP socket in the network namespace...

GHSA-V8FW-85R8-5M23 Deno: Node TCPWrap numeric hostname aliases bypass --deny-net resolved-IP deny checks

Summary Deno's network permission model is designed so that --deny-net rules apply to the resolved IP address of a destination, not just the literal string supplied by the caller. That means --deny-net=127.0.0.1 or --deny-net=127.0.0.0/8 is expected to block any attempt to reach loopback,...

Deno: WebSocket API sandbox bypass via missing post-DNS check

Summary When a WebSocket connection was opened, Deno checked the destination hostname against --deny-net rules but did not re-check the IP addresses that hostname resolved to. An attacker-controlled script could use a specially crafted domain name that passes the hostname check yet resolves to a...
