Log Message:
Security fix for SA17028:

"A vulnerability in Weex can be exploited by malicious users to cause a DoS
(Denial of Service) or to compromise a vulnerable system.

The vulnerability is caused due to a format string error in the \ 
"log_flush()"
function when flushing an error log entry that contains format string
specifiers to disk. This may be exploited to execute arbitrary code on a
user's system via a directory name containing format string specifiers.

Successful exploitation requires that the attacker is able to create
directories within the user's Weex home directory."
