This update fixes a number of security issues in PHP.

A number of buffer overflow flaws were found in the PHP session extension, the str_replace() function, and the imap_mail_compose() function. If very long strings under the control of an attacker are passed to the str_replace() function then an integer overflow could occur in memory allocation. If a script uses the imap_mail_compose() function to create a new MIME message based on an input body from an untrusted source, it could result in a heap overflow. An attacker who is able to access a PHP application affected by any these issues could trigger these flaws and possibly execute arbitrary code as the ‘apache’ user. (CVE-2007-0906)

If unserializing untrusted data on 64-bit platforms, the zend_hash_init() function can be forced to enter an infinite loop, consuming CPU resources for a limited length of time, until the script timeout alarm aborts execution of the script. (CVE-2007-0988)

If the wddx extension is used to import WDDX data from an untrusted source, certain WDDX input packets may allow a random portion of heap memory to be exposed. (CVE-2007-0908)

If the odbc_result_all() function is used to display data from a database, and the contents of the database table are under the control of an attacker, a format string vulnerability is possible which could lead to the execution of arbitrary code. (CVE-2007-0909)

A one byte memory read will always occur before the beginning of a buffer, which could be triggered for example by any use of the header() function in a script. However it is unlikely that this would have any effect. (CVE-2007-0907)

Several flaws in PHP could allows attackers to ‘clobber’ certain super-global variables via unspecified vectors. (CVE-2007-0910)

The Fedora Project would like to thank Stefan Esser for his help diagnosing these issues.
