The flaw happens because the floating point conversion is using system functions without the correct boundary checks.
If there are any application that accepts a format string from the outside without necessary input filtering, it could allow remote attacks.
This flaw does not exist in the command line tool.
For Debian 7 Wheezy, these problems have been fixed in version 7.26.0-1+wheezy18.
We recommend that you upgrade your curl packages.
