Description Joe Orton 2007-05-15 15:45:36 UTC
Description of problem:
The shmop functions in PHP before 4.4.5, and before 5.2.1 in the 5.x series, do
not verify that their arguments correspond to a shmop resource, which allows
context-dependent attackers to read and write arbitrary memory locations via
arguments associated with an inappropriate resource, as demonstrated by a GD
Image resource.

Comment 1 Joe Orton 2007-05-15 15:46:38 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-2007-1376 can only be triggered by a script author;
since no trust boundary is crossed, this issue is not treated as security-sensitive.
