Package: zebra
Vulnerability: denial of service
OpenPKG Specific: no
Affected Releases: Affected Packages: Corrected Packages:
OpenPKG CURRENT <= zebra-0.93b-20031001 >= zebra-0.93b-20031113
OpenPKG 1.3 <= zebra-0.93b-1.3.0 >= zebra-0.93b-1.3.1

Description:
Jonny Robertson reported [0] that Zebra can be remotely crashed if a
remote attacker can connect to the Zebra telnet management ports. The
Common Vulnerabilities and Exposures (CVE) project assigned the id
CAN-2003-0795 [1] to the problem.
Herbert Xu reported [2] that Zebra can accept spoofed messages sent
on the kernel netlink interface by other users on the local machine.
The Common Vulnerabilities and Exposures (CVE) project assigned the id
CAN-2003-0858 [3] to the problem.
Please check whether you are affected by running "<prefix>/bin/rpm -q
zebra". If you have the "zebra" package installed and its version is
affected (see above), we recommend that you immediately upgrade it
(see Solution). [4][5]
Solution:
Select the updated source RPM appropriate for your OpenPKG release
[6][7], fetch it from the OpenPKG FTP service [8][9] or a mirror
location, verify its integrity [10], build a corresponding binary
RPM from it [4] and update your OpenPKG installation by applying the
binary RPM [5]. 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 zebra-0.93b-1.3.1.src.rpm
ftp> bye
$ <prefix>/bin/rpm -v --checksig zebra-0.93b-1.3.1.src.rpm
$ <prefix>/bin/rpm --rebuild zebra-0.93b-1.3.1.src.rpm
$ su -
# <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/zebra-0.93b-1.3.1.*.rpm
