This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.
PHP 4.0.0 through 4.4.6 and 5.0.0 through 5.2.1 allows context-dependent attackers to read arbitrary memory locations via an interruption that triggers a user space error handler that changes a parameter to an arbitrary pointer, as demonstrated via the iptcembed function, which calls certain convert_to_* functions with its input parameters.
View Analysis Description
Access Vector (AV):
Access Complexity (AC):
Allows unauthorized disclosure of information
The PHP interpreter does not offer a reliable "sandboxed" security
layer (as found in, say, a JVM) in which untrusted scripts can be run;
any script run by the PHP interpreter must be trusted with the
privileges of the interpreter itself. We therefore do not classify
this issue as security-sensitive since no trust boundary is crossed.
