Description:
Ulf Harnhammar has reported a vulnerability in Weex, which potentially 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.
The vulnerability has been reported in version 2.6.1.5. Other versions may also be affected.
Solution:
Restrict use to trusted servers only.
Provided and/or discovered by:
Ulf Harnhammar, Debian Security Audit Project
