| Description: |
From the Pardus advisory:
The extract function in PHP before 5.2.15 does not prevent use of the
EXTR_OVERWRITE parameter to overwrite (1) the GLOBALS superglobal array
and (2) the this variable, which allows context-dependent attackers to
bypass intended access restrictions by modifying data structures that
were not intended to depend on external input. (CVE-2011-0752)
Race condition in the PCNTL extension in PHP before 5.3.4, when a
user-defined signal handler exists, might allow context-dependent
attackers to cause a denial of service (memory corruption) via a large
number of concurrent signals. (CVE-2011-0753)
Integer overflow in the mt_rand function in PHP before 5.3.4 might make
it easier for context-dependent attackers to predict the return values
by leveraging a script's use of a large max parameter, as demonstrated
by a value that exceeds mt_getrandmax. (CVE-2011-0755)
