CVE-2022-36113: 
Rust vulnerability analysis and mitigation

CVE-2022-36113 is a security vulnerability discovered in Cargo, Rust's package manager, affecting all versions prior to 0.65.0. The vulnerability was disclosed on September 14, 2022, and a fix was included in Rust 1.64, released on September 22, 2022. The issue specifically affects users of alternate registries, while users relying on crates.io are not impacted (Rust Blog).

The vulnerability occurs during package extraction in the ~/.cargo folder. When Cargo extracts a package, it writes 'ok' to a .cargo-ok file to indicate successful extraction. The vulnerability allowed packages to contain a malicious .cargo-ok symbolic link, which when extracted, would cause Cargo to overwrite the first two bytes of the file the symlink pointed to with 'ok'. This vulnerability has been assigned a CVSS score of 4.8 with high attack complexity and requires user interaction (Oracle Security, GitHub Advisory).

The vulnerability allows an attacker who can upload packages to an alternate registry to corrupt arbitrary files on the machine using Cargo to extract the package. While classified as 'low' severity, it's important to note that Cargo already allows code execution at build time through build scripts and procedural macros, making this vulnerability a subset of existing potential damage vectors (Rust Blog).

The vulnerability was fixed in Rust 1.64 (Cargo 0.65.0). For users of alternate registries, the recommended mitigation is to exercise care in package selection and only include trusted dependencies. Patch files for Rust 1.63.0 were made available in the wg-security-response repository for users building their own toolchains (Rust Blog).
