The remote host is affected by the vulnerability described in GLSA-200506-10 (LutelWall: Insecure temporary file creation)

Eric Romang has discovered that the new_version_check() function     in LutelWall insecurely creates a temporary file when updating to a new     version.

Impact :

A local attacker could create symbolic links in the temporary file     directory, pointing to a valid file somewhere on the filesystem. When     the update script is executed (usually by the root user), this would     result in the file being overwritten with the rights of this user.

Workaround :

There is no known workaround at this time.
