Synopsis |
| 17 |
======== |
| 18 |
|
| 19 |
Multiple vulnerabilities were found in PHP, the worst of which leading |
| 20 |
to the remote execution of arbitrary code. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
PHP is a widely-used general-purpose scripting language that is |
| 26 |
especially suited for Web development and can be embedded into HTML. |
| 27 |
|
| 28 |
Affected packages |
| 29 |
================= |

------------------------------------------------------------------- |
| 32 |
Package / Vulnerable / Unaffected |

Description |
| 37 |
=========== |
| 38 |
|
| 39 |
Multiple vulnerabilities have been discovered in PHP. Please review the |
| 40 |
CVE identifiers referenced below and the associated PHP release notes |
| 41 |
for details. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
A context-dependent attacker could execute arbitrary code via a |
| 47 |
specially crafted string containing an HTML entity when the mbstring |
| 48 |
extension is enabled. Furthermore a remote attacker could execute |
| 49 |
arbitrary code via a specially crafted GD graphics file. |
| 50 |
|
| 51 |
A remote attacker could also cause a Denial of Service via a malformed |
| 52 |
string passed to the json_decode() function, via a specially crafted |
| 53 |
ZIP file passed to the php_zip_make_relative_path() function, via a |
| 54 |
malformed JPEG image passed to the exif_read_data() function, or via |
| 55 |
temporary file exhaustion. It is also possible for an attacker to spoof |
| 56 |
certificates, bypass various safe_mode and open_basedir restrictions |
| 57 |
when certain criteria are met, perform Cross-site scripting attacks, |
| 58 |
more easily perform SQL injection attacks, manipulate settings of other |
| 59 |
virtual hosts on the same server via a malicious .htaccess entry when |
| 60 |
running on Apache, disclose memory portions, and write arbitrary files |
| 61 |
via a specially crafted ZIP archive. Some vulnerabilities with unknown |
| 62 |
impact and attack vectors have been reported as well. |
| 63 |
|
| 64 |
Workaround |
| 65 |
========== |
| 66 |
|
| 67 |
There is no known workaround at this time. |
| 68 |
|
| 69 |
Resolution |
| 70 |
========== |
| 71 |
|
| 72 |
All PHP users should upgrade to the latest version. As PHP is |
| 73 |
statically linked against a vulnerable version of the c-client library |
| 74 |
when the imap or kolab USE flag is enabled (GLSA 200911-03), users |
| 75 |
should upgrade net-libs/c-client beforehand: |
| 76 |
|
| 77 |
# emerge --sync |
| 78 |
# emerge --ask --oneshot --verbose ">=net-libs/c-client-2007e" |
| 79 |
# emerge --ask --oneshot --verbose ">=dev-lang/php-5.2.12" |
| 80 |
