Synopsis |
16 |
======== |
17 |
|
18 |
PHP makes use of an affected PCRE library and ships with an affected |
19 |
XML-RPC library and is therefore potentially vulnerable to remote |
20 |
execution of arbitrary code. |
21 |
|
22 |
Background |
23 |
========== |
24 |
|
25 |
PHP is a general-purpose scripting language widely used to develop |
26 |
web-based applications. It can run inside a web server using the |
27 |
mod_php module or the CGI version of PHP, or can run stand-alone in a |
28 |
CLI. |

Description |
47 |
=========== |
48 |
|
49 |
PHP makes use of a private copy of libpcre which is subject to an |
50 |
integer overflow leading to a heap overflow (see GLSA 200508-17). It |
51 |
also ships with an XML-RPC library affected by a script injection |
52 |
vulnerability (see GLSA 200508-13). |
53 |
|
54 |
Impact |
55 |
====== |
56 |
|
57 |
An attacker could target a PHP-based web application that would use |
58 |
untrusted data as regular expressions, potentially resulting in the |
59 |
execution of arbitrary code. If web applications make use of the |
60 |
XML-RPC library shipped with PHP, they are also vulnerable to remote |
61 |
execution of arbitrary PHP code. |
62 |
|
63 |
Workaround |
64 |
========== |
65 |
|
66 |
There is no known workaround at this time. |
67 |
|
68 |
Resolution |
69 |
========== |
70 |
|
71 |
All PHP users should upgrade to the latest version: |
72 |
|
73 |
# emerge --sync |
74 |
# emerge --ask --oneshot --verbose dev-php/php |
75 |
|
76 |
All mod_php users should upgrade to the latest version: |
77 |
|
78 |
# emerge --sync |
79 |
# emerge --ask --oneshot --verbose dev-php/mod_php |
80 |
|
81 |
All php-cgi users should upgrade to the latest version: |
82 |
|
83 |
# emerge --sync |
84 |
# emerge --ask --oneshot --verbose dev-php/php-cgi |
85 |
