The Amazon Kindle Touch before 5.1.2 does not properly restrict access to the libkindleplugin.so NPAPI plugin interface, which might allow remote attackers to have an unspecified impact via vectors involving the (1) dev.log, (2) lipc.set, (3) lipc.get, or (4) todo.scheduleItems method, a different vulnerability than CVE-2012-4249.

The Amazon Lab126 com.lab126.system sendEvent implementation on the Kindle Touch before 5.1.2 allows context-dependent attackers to execute arbitrary commands via shell metacharacters in a string, as demonstrated by using lipc-set-prop to set an LIPC property, a different vulnerability than CVE-2012-4248.
