CVE-2015-4641

TITLE

Samsung Galaxy S phones fail to properly validate SwiftKey language pack updates

Trust: 0.8

sources: CERT/CC: VU#155412

DESCRIPTION

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. Samsung Galaxy S4 and so on are all smart mobile devices released by South Korea's Samsung. A directory traversal vulnerability exists in the implementation of the SwiftKey language-pack upgrade for several Samsung Galaxy devices. SwiftKey is prone to a directory-traversal vulnerability. This may aid in further attacks
