Description Jan Lieskovsky 2010-07-22 12:03:41 UTC
Common Vulnerabilities and Exposures assigned an identifier CVE-2010-1914 to
the following vulnerability:

The Zend Engine in PHP 5.2 through 5.2.13 and 5.3 through 5.3.2
allows context-dependent attackers to obtain sensitive information
by interrupting the handler for the (1) ZEND_BW_XOR opcode
(shift_left_function), (2) ZEND_SL opcode (bitwise_xor_function),
or (3) ZEND_SR opcode (shift_right_function), related to the
convert_to_long_base function.

Statement:

Red Hat does not consider interruption issues allowing safe_mode / open_basedir
restriction bypass to be security sensitive.  For more details see
