RUSTSEC-2024-0403: 
Rust vulnerability analysis and mitigation

A vulnerability was discovered in the Deno core runtime (RUSTSEC-2024-0403) where an exposed op_panic operation in the base runtime could be exploited to force a panic in the runtime's containing thread. The issue was identified and reported on July 18, 2024 (GitHub Issue).

The vulnerability stems from the Deno.core.ops.op_panic operation being available by default in the runtime environment. When called, this operation can force a panic in the thread containing the runtime, which breaks the intended sandboxing mechanisms (GitHub Issue).

The exploitation of this vulnerability could lead to a Denial of Service (DoS) condition by forcing panics in the runtime's containing thread. This violates the sandbox isolation principles that should prevent such direct runtime manipulation (GitHub Issue).

A workaround has been proposed to stub out the panic operation by implementing: Deno.core.ops.op_panic = (msg) => { throw new Error(msg) }; This modification prevents the direct panic in the runtime thread while maintaining error handling functionality (GitHub Issue).
