Synopsis |
16 |
======== |
17 |
|

19 |
processing regular expressions. |

|
21 |
Background |
22 |
========== |
23 |
|
24 |
Mod_perl is an Apache module that embeds the Perl interpreter within |
25 |
the server, allowing Perl-based web-applications to be created. |

Description |
39 |
=========== |
40 |
|
41 |
Alex Solvey discovered that the "path_info" variable used in file |
42 |
RegistryCooker.pm (mod_perl 2.x) or file PerlRun.pm (mod_perl 1.x), is |
43 |
not properly escaped before being processed. |
44 |
|
45 |
Impact |
46 |
====== |
47 |
|
48 |
A remote attacker could send a specially crafted URL to the vulnerable |
49 |
server, possibly resulting in a massive resource consumption. |
50 |
|
51 |
Workaround |
52 |
========== |
53 |
|
54 |
There is no known workaround at this time. |
55 |
|
56 |
Resolution |
57 |
========== |
58 |
|
59 |
All mod_perl 1.x users should upgrade to the latest version: |
60 |
|
61 |
# emerge --sync |
62 |
# emerge --ask --oneshot --verbose ">=www-apache/mod_perl-1.30" |
63 |
|
64 |
All mod_perl 2.x users should upgrade to the latest version: |
