Background
The Rust Programming Language Standard Library is a core component of the Rust programming language. It provides a set of common tools and functionality for Rust developers. The library is widely used in various applications and frameworks. However, versions 1.34.x before 1.34.2 of the library contain a memory safety vulnerability that can be exploited if the Error::type_id method is overridden. This can lead to memory unsafety and potential out-of-bounds write or read vulnerabilities in safe code.
Vulnerability Detail
The vulnerability (CVE-2019-12083) arises from a stabilized method in the Rust Programming Language Standard Library. If the Error::type_id method is overridden, it allows any type to be safely cast to any other type, violating Rust's safety guarantees. This can result in memory safety vulnerabilities, such as out-of-bounds write or read. It is important to note that code that does not manually implement Error::type_id is unaffected by this vulnerability.
