SCA: security update for jaraco.context (GHSA-58pv-8j8x-9vj2)

high Tenable Cloud Security Plugin ID 436739

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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. (CVE-2026-23949)
