CVE-2014-3686: Input Validation
First published: Fri Oct 10 2014(Updated: )
Jouni Malinen discovered that a string supplied from a remote device could be supplied to a system() call in wpa_cli or hostapd_cli when running an action script (with the "-a" option), resulting in arbitrary command execution. This issue could also be triggered by an attacker within radio range. Patches are available from the following: <a href="http://w1.fi/security/2014-1/">http://w1.fi/security/2014-1/</a> Based on the information about affected configurations in the upstream advisory, Red Hat Enterprise Linux 5 is likely to be not vulnerable, but Red Hat Enterprise Linux 6 and 7 are likely to be vulnerable. Acknowledgements: Red Hat would like to thank Jouni Malinen for reporting this issue.
