Debian Security Advisory 5784-1

Debian Linux Security Advisory 5784-1 - Fabian Vogt reported that the PAM module in oath-toolkit, a collection of components to build one-time password authentication systems, does not safely perform file operations in users's home directories when using the usersfile feature (allowing to place the OTP state in the home directory of the to-be-authenticated user). A local user can take advantage of this flaw for root privilege escalation.
