Description:
According to Florian Heinz [0] a remote code execution vulnerability
exists in the QPopper POP3 server [1]. Attackers may remotely exploit
this vulnerability to execute arbitrary code under the user id of a
mailbox owner and the "mail" group id.
Please check whether you are affected by running "<prefix>/bin/rpm -q
qpopper". If you have the "qpopper" package installed and its version
is affected (see above), we recommend that you immediately upgrade it
(see Solution). [2][3]
Solution:
Select the updated source RPM appropriate for your OpenPKG release
[4][5], fetch it from the OpenPKG FTP service [6][7] or a mirror
location, verify its integrity [8], build a corresponding binary RPM
from it [2] and update your OpenPKG installation by applying the
binary RPM [3]. For the current release OpenPKG 1.2, perform the
following operations to permanently fix the security problem (for
other releases adjust accordingly).
$ ftp ftp.openpkg.org
ftp> bin
ftp> cd release/1.2/UPD
ftp> get qpopper-4.0.4-1.2.1.src.rpm
ftp> bye
$ <prefix>/bin/rpm -v --checksig qpopper-4.0.4-1.2.1.src.rpm
$ <prefix>/bin/rpm --rebuild qpopper-4.0.4-1.2.1.src.rpm
$ su -
# <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/qpopper-4.0.4-1.2.1.*.rpm
