Summary

python-pip security update

Details

pip is the package installer for Python. You can use pip to install packages from the Python Package Index and other indexes. %global bashcompdir %(b=$(pkg-config --variable=completionsdir bash-completion 2>/dev/null); echo ${b:-/bash_completion.d}) Name: python-pip Version: 23.3.1 Release: 6 Summary: A tool for installing and managing Python packages License: MIT and Python and ASL 2.0 and BSD and ISC and LGPLv2 and MPLv2.0 and (ASL 2.0 or BSD) URL: http://www.pip-installer.org Source0: Source1: pip.loongarch.conf BuildArch: noarch Patch1: remove-existing-dist-only-if-path-conflicts.

Security Fix(es):

When pip is installing and extracting a maliciously crafted wheel archive, files may be extracted outside the installation directory. The path traversal is limited to prefixes of the installation directory, thus isn't able to inject or overwrite executable files in typical situations.(CVE-2026-1703)
