Name of the Vulnerable Software and Affected Versions:
fast-float (affected versions not specified)
Description:
The issue arises from the
fast float::common::AsciiStr::first method within the AsciiStr struct, which uses the unsafe keyword to read from memory without performing bounds checking. It directly dereferences a pointer offset by self.ptr. This leads to accessing an invalid memory address when an empty string is provided as input, violating Rust's memory safety guarantees.Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
