Canonical published in a security notice details about the Light Display Manager vulnerability in its Ubuntu 13.10 (Saucy Salamander) operating system.

According to the company, Light Display Manager could have been made to expose sensitive information locally.

It has been discovered that Light Display Manager incorrectly applied the AppArmor security profile when the Guest account was used. A local attacker could have used this issue to possibly gain access to sensitive information.
