Description Joe Orton 2007-05-15 15:39:01 UTC

Description of problem:
Integer overflow in the 16 bit variable reference counter in PHP 4 allows
context-dependent attackers to execute arbitrary code by overflowing this
counter, which causes the same variable to be destroyed twice, a related issue
to CVE-2007-1286.

Comment 1 Joe Orton 2007-05-15 15:42:27 UTC

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.  

This bug described in CVE-2007-1383 can only be triggered by a script author;
since no trust boundary is crossed, this issue is not treated as security-sensitive.
