Description:
According to a posting on Bugtraq [1], Shaun Colley discovered and
researched a stack-based buffer overflow vulnerability which exists in
the GNU Sharutils [2] due to lack of bounds checking when handling the
'-o' command-line option.
Please check whether you are affected by running "<prefix>/bin/rpm
-q sharutils". If you have the "sharutils" 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 most recent release OpenPKG 2.0, perform the
following operations to permanently fix the security problem (for
other releases adjust accordingly).
$ ftp ftp.openpkg.org
ftp> bin
ftp> cd release/2.0/UPD
ftp> get sharutils-4.2.1-2.0.1.src.rpm
ftp> bye
$ <prefix>/bin/openpkg rpm -v --checksig sharutils-4.2.1-2.0.1.src.rpm
$ <prefix>/bin/openpkg rpm --rebuild sharutils-4.2.1-2.0.1.src.rpm
$ su -
# <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/sharutils-4.2.1-2.0.1.*.rpm
