USN-99-1 fixed a safe mode bypass which allowed malicious PHP scripts
to circumvent path restrictions by creating a specially crafted
directory whose length exceeded the capacity of the realpath()
function (CAN-2004-1064). However, this caused severe regressions,
some applications like SquirrelMail and Gallery did not work any
more, and the package ‘php4-pear’ was empty. The current version
repairs this.
In addition this update fixes a crash of the PHP interpreter if
curl_init() was called with a non-string argument. Please note that
this is not security relevant since this condition usually cannot be
triggered externally.
