php: multiple vulnerabilities

Package(s):mod_php php-cli php-common CVE #(s):CVE-2011-0752 CVE-2011-0753 CVE-2011-0755
Created:February 14, 2011 Updated:April 5, 2011
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)
