jaraco.context Has a Path Traversal Vulnerability

jaraco.context, an open-source software package that provides some useful decorators and context managers, has a Zip Slip path traversal vulnerability in the `jaraco.context.tarball()` function starting in version 5.2.0 and prior to version 6.1.0. The vulnerability may allow attackers to extract files outside the intended extraction directory when malicious tar archives are processed. The strip_first_component filter splits the path on the first `/` and extracts the second component, while allowing `../` sequences. Paths like `dummy_dir/../../etc/passwd` become `../../etc/passwd`. Note that this suffers from a nested tarball attack as well with multi-level tar files such as `dummy_dir/inner.tar.gz`, where the inner.tar.gz includes a traversal `dummy_dir/../../config/.env` that also gets translated to `../../config/.env`. Version 6.1.0 contains a patch for the issue.

对路径名的限制不恰当(路径遍历)

jaraco.context 路径遍历漏洞

jaraco.context是Jason R. Coombs个人开发者的一个Python库。 jaraco.context 5.2.0版本至6.1.0之前版本存在路径遍历漏洞，该漏洞源于tarball函数存在Zip Slip路径遍历，可能导致提取恶意tar存档时文件被提取到预期目录之外。
