Description of problem:
1. 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 the script  (CVE-NO-NAME)

2. If a script uses the imap_mail_compose() function to create a new MIME
message based on an input body from an untrusted source, an attacker may be able
to force a heap overflow (CVE-2006-0906)

3. If the format string could passed to one of the functions in the printf()
family could be controlled by an attacker via untrusted data, then an
out-of-bounds memory read could crash the Apache child process (CVE-2006-0909)

4. If very long strings are passed to the str_replace() function then an integer
overflow could occur in memory allocation, which could lead to a heap buffer
overflow.  (CVE-2006-0906)

5. 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-2006-0908)

6. 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.
(CVE-2006-0909)

7. Unspecified stack overflows and stack corruptions, and super-global clobbers
vulnerabilities in the session extension.  (CVE-2006-0906, CVE-2006-0910)

Affects: RHEL3, RHEL4
