CVE-2015-4641 (CCN-104835)

Assigned:2015-06-16
Published:2015-06-16
Updated:2016-12-07
Summary:Directory traversal vulnerability in the SwiftKey language-pack update implementation on Samsung Galaxy S4, S4 Mini, S5, and S6 devices allows remote web servers to write to arbitrary files, and consequently execute arbitrary code in a privileged context, by leveraging control of the skslm.swiftkey.net domain name and providing a .. (dot dot) in an entry in a ZIP archive, as demonstrated by a traversal to the /data/dalvik-cache directory.
