=========================================================== Ubuntu Security Notice USN-99-2 March 24, 2005 php4 vulnerabilities CAN-2004-1064 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 4.10 (Warty Warthog) The following packages are affected: libapache2-mod-php4 php4-cgi The problem can be corrected by upgrading the affected package to version 4:4.3.8-3ubuntu7.6. In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: 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.
