Improper Input Validation


Severity High
Score 7.8/10


The package fails to perform sufficient validation of snap content interface and layout paths, resulting in the ability for snaps to inject arbitrary "AppArmor" policy rules via malformed content interface and layout declarations and hence escape strict snap confinement. This issue affects package versions prior to 2.54.3, and 3.9.9-0sdhd5.
