OpenPKG Security Advisory The OpenPKG Project

openpkg-security@openpkg.org openpkg@openpkg.org
OpenPKG-SA-2003.045 19-Oct-2003
________________________________________________________________________
Package: ircd
Vulnerability: remote denial of service vulnerability
OpenPKG Specific: no
Affected Releases: Affected Packages: Corrected Packages:
OpenPKG CURRENT <= ircd-2.10.3p3-20030725 >= ircd-2.10.3p4-20031012
OpenPKG 1.3 <= ircd-2.10.3p3-1.3.0 >= ircd-2.10.3p3-1.3.1
OpenPKG 1.2 <= ircd-2.10.3p3-1.2.0 >= ircd-2.10.3p3-1.2.1
Dependent Packages: none
Description:
 According to a report from Piotr Kucharski [0] a buffer overflow
 vulnerability exists in ircd [1] that allows a remote attacker to
 crash the ircd server, thus causing a denial of service condition.
 The Common Vulnerabilities and Exposures (CVE) project assigned the id
 CAN-2003-0864 [2] to the problem.
 Please check whether you are affected by running "<prefix>/bin/rpm -q
 ircd". If you have the "ircd" 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 ircd-2.10.3p3-1.3.1.src.rpm
 ftp> bye
 $ <prefix>/bin/rpm -v --checksig ircd-2.10.3p3-1.3.1.src.rpm
 $ <prefix>/bin/rpm --rebuild ircd-2.10.3p3-1.3.1.src.rpm
 $ su -
 # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/ircd-2.10.3p3-1.3.1.*.rpm
