Description:
Several vulnerabilities were reported in PHP. A remote or local user may be able to execute arbitrary code on the target system or cause denial of service conditions.
Several buffer overflows exist in some PHP functions [CVE-2007-0906]. The PHP session extension, the str_replace() function, and the imap_mail_compose() functions are affected. A remote user may be able to submit specially crafted values to a program that uses the affected function to trigger an overflow and execute arbitrary code.
A buffer underflow in the sapi_header_op() function may let users cause denial of service conditions [CVE-2007-0907].
The wddx extension can be exploited using certain WDDX input packets to view random portions of heap memory [CVE-2007-0908].
A remote user under control of a database table accessed via the odbc_result_all() function can supply specially crafted data to trigger a format string flaw and execute arbitrary code [CVE-2007-0909].
Unspecified vulnerabilities may allow a user to overwrite certain super-global variables [CVE-2007-0910].
A user can supply specially crafted data to the zend_hash_init() function to cause the function to enter an infinite loop and consume excessive CPU resources until a timeout is reached [CVE-2007-0988].
