An insufficient environment sanitization flaw was found in the way 'abrt-action-install-debuginfo-to-abrt-cache' tool, performing installation of required debuginfo packages into ABRT's cache, of ABRT, an automatic bug detection and reporting tool, used the PYTHONPATH environment variable. A local attacker could provide a commonly used Python module with specially-crafted content in non-standard system location / path, which would lead into arbitrary Python code execution with privileges of the 'abrt' user, when the 'abrt-action-install-debuginfo-to-abrt-cache' tool was run from the parent directory of the folder, containing the malicious module.
