Threats affecting pkg:github/qsnapper

Incorrect caching of authentication between different users of the  qSnapper dbus service before version 1.3.3 allowed any local attacker to use dbus functions after a privileged users has authenticated for them.

Incorrect caching of authentication between different polkit methods in qSnapper before version 1.3.3 allowed a local attacker to use functions like "restore from snapshot" even if only allowed to do "delete snapshot".

Lack of authentication when using the "snapshot diff" functions in qSnapper before version 1.3.3 allowed a local attacker to see otherwise read protected information.

A path traversal attack when using a "configName" parameter in qSnapper before version 1.3.3 allowed a local attacker to use malicious config files for snapper and so cause a denial of service or potentially escalate privileges to root.

A time-to-check-time-of-use in polkit authentication of qSnapper before version 1.3.3 allowed a local attacker to bypass qSnappers authentication mechanism and operate e.g. as root user.
