pip show sosreport

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2015-7529, inspect your installed packages using pip:

pip show sosreport

Analyze the terminal output to locate any version of Sosreport in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.3), your application is affected.

Note: The pip show sosreport command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-59: Improper Link Resolution Before File Access ('Link Following'), where the product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource. In Sosreport, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

sosreport in SoS 3.x allows local users to obtain sensitive information from sosreport files or gain privileges via a symlink attack on an archive file in a temporary directory, as demonstrated by `sosreport-$hostname-$date.tar` in `/tmp/sosreport-$hostname-$date`.
