"Ubuntu Security Notice USN-66-1 described a circumvention of the
'open_basedir' restriction by using the cURL module. Adam Conrad
discovered that the fix from USN-66-1 still allowed to bypass this
restriction with certain variants of path specifications.

In addition this update fixes the crash of the PHP interpreter if
curl_init() was called without parameters.

For reference, this is the relevant part of the original advisory :

FraMe from kernelpanik.org reported that the cURL module does not
respect open_basedir restrictions. As a result, scripts which used
cURL to open files with an user-specified path could read arbitrary
local files outside of the open_basedir directory.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
