Description:
According to security advisory CESA-2004-006 from Chris Evans, the
libtiff [0] image en-/decoder suffers from several heap based buffer
overflows. The Common Vulnerabilities and Exposures (CVE) project
assigned the id CAN-2004-0803 [1] to the problem.
Other code reviewers found integer overflows which affect memory
allocation. The Common Vulnerabilities and Exposures (CVE) project
assigned the id CAN-2004-0886 [2] to the problem.
Please check whether you are affected by running "/bin/openpkg
rpm -q tiff". If you have the "tiff" package installed and its version
is affected (see above), we recommend that you immediately upgrade it
(see Solution) and its dependent packages (see above), if any, too
[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 most recent release OpenPKG 2.1, perform the
following operations to permanently fix the security problem (for
other releases adjust accordingly).
$ ftp ftp.openpkg.org
ftp> bin
ftp> cd release/2.1/UPD
ftp> get tiff-3.6.1-2.1.1.src.rpm
ftp> bye
$ /bin/openpkg rpm -v --checksig tiff-3.6.1-2.1.1.src.rpm
$ /bin/openpkg rpm --rebuild tiff-3.6.1-2.1.1.src.rpm
$ su -
# /bin/openpkg rpm -Fvh /RPM/PKG/tiff-3.6.1-2.1.1.*.rpm
Additionally, we recommend that you rebuild and reinstall
all dependent packages (see above), if any, too [3][4].
