Summary

pam_usb: getenv() used in PAM context allows environment variable injection into local-check logic

Details

pamusb provides hardware authentication for Linux using removable media. In versions prior to 0.9.2, getenv() environment variables XRDPSESSION, DISPLAY and TMUX allow environment variable injection into local-check logic. These environment variables influence whether a current session is local or remote, and a PAM module that runs in the context of setuid binaries (sudo, su), getenv() returns attacker-controlled values whenever the process environment has been manipulated by a local user. This issue has been fixed in version 0.9.2.
