Description Agostino Sarubbo gentoo-dev 2014-07-12 19:21:23 UTC
From ${URL} :


Two vulnerabilities have been reported in PHP, which can be exploited by malicious, local users to gain escalated privileges.

1) A use-after-free error related to SPL iterators can be exploited to corrupt memory.

2) A use-after-free error related to ArrayIterators can be exploited to corrupt memory.

Successful exploitation may allow execution of arbitrary code with e.g. web server's privileges by executing a specially crafted PHP 
script within Apache HTTP server context.

The vulnerabilities are reported in version 5.5.14. Other versions may also be affected.

Fixed in the source code repository.

Provided and/or discovered by:
insighti within bug entries.

Original Advisory:

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.

CVE-2014-4670 (
  Use-after-free vulnerability in ext/spl/spl_dllist.c in the SPL component in
  PHP through 5.5.14 allows context-dependent attackers to cause a denial of
  service or possibly have unspecified other impact via crafted iterator usage
