Publication date

Overview
PHP vulnerability
Releases
Details
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.
