Rust是Mozilla基金会的一款通用、编译型编程语言。 Mozilla Rust 存在安全漏洞，该漏洞源于文件扩展名的安全相关验证可能会受到影响。 用于转换为字符串的 NSString 方法可能会返回部分结果。 因为它们在指向字符串缓冲区的指针上调用 CStr::from_ptr，所以字符串在第一个 0 字节处终止，这可能不是字符串的结尾。

Vulnerability Description
An issue was discovered in the fruity crate through 0.2.0 for Rust. Security-relevant validation of filename extensions is plausibly affected. Methods of NSString for conversion to a string may return a partial result. Because they call CStr::from_ptr on a pointer to the string buffer, the string is terminated at the first '\0' byte, which might not be the end of the string.
