Description:
According to a security advisory [0] from obscure (at) eyeonsecurity (dot) org [email concealed] a
cross site scripting vulnerability exists in the start_form() function
from CGI.pm [1]. The Common Vulnerabilities and Exposures (CVE)
project assigned the id CAN-2003-0615 [2] to the problem.
Note that beginning with perl-www-20030609-20030609 and
perl-www-1.3.0-1.3.0 a preliminary vendor patch was already included
which fixes the specific issue discussed in the original advisory. Our
corrected packages now include the more generalized patch the author
uses in his latest version.
Please check whether you are affected by running "<prefix>/bin/rpm
-q perl-www". If you have the "perl-www" package installed and its
version is affected (see above), we recommend that you immediately
upgrade it (see Solution). [3][4]
Solution:
Select the updated source RPM appropriate for your OpenPKG release
[5][6], fetch it from the OpenPKG FTP service [7][8] or a mirror
location, verify its integrity [9], build a corresponding binary RPM
from it [3] and update your OpenPKG installation by applying the
binary RPM [4]. For the current release OpenPKG 1.3, perform the
following operations to permanently fix the security problem (for
other releases adjust accordingly).
$ ftp ftp.openpkg.org
ftp> bin
ftp> cd release/1.3/UPD
ftp> get perl-www-1.3.1-1.3.1.src.rpm
ftp> bye
$ <prefix>/bin/rpm -v --checksig perl-www-1.3.1-1.3.1.src.rpm
$ <prefix>/bin/rpm --rebuild perl-www-1.3.1-1.3.1.src.rpm
$ su -
