Descriptions
pam-python before 1.0.7-1 has an issue in regard to the default environment variable handling of Python, which could allow for local root escalation in certain PAM setups.
pam-python versiones anteriores a 1.0.7-1, presenta un problema con respecto al manejo predeterminado de la variable de entorno de Python, lo que podría permitir la escalada de root local en ciertas configuraciones de PAM.
USN-4552-1 and USN-4552-2 fixed a vulnerability in Pam-python. The update introduced a regression which prevented PAM modules written in Python from importing python modules from site-specific directories. Malte Kraus discovered that Pam-python mishandled certain environment variables. A local attacker could potentially use this vulnerability to execute programs as root. Various other issues were also addressed.
