-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ OpenPKG Security Advisory The OpenPKG Project http://www.openpkg.org/security.html http://www.openpkg.org firstname.lastname@example.org email@example.com OpenPKG-SA-2004.002 16-Jan-2004 ________________________________________________________________________ Package: tcpdump Vulnerability: denial of service OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= tcpdump-3.8.1-20040108 >= tcpdump-3.8.1-20040116 OpenPKG 1.3 <= tcpdump-3.7.2-1.3.0 >= tcpdump-3.7.2-1.3.1 OpenPKG 1.2 <= tcpdump-3.7.1-1.2.1 >= tcpdump-3.7.1-1.2.2 Dependent Packages: none Description: A bunch of vulnerabilities in tcpdump  were found and addressed in the past. All of them are in the area of packet decoding. Faulty decoder functions can result in denial of service attacks through infinite loops, memory starvation and application crashes. In the worst case arbitrary code execution is possible. This OpenPKG update resolves all issues currently known, as shown in the following table: tcpdump 371 371 372 381 OpenPKG 120 121 130 20020822 --- --- --- --- CAN-2002-0380  nfs X - - - see past OpenPKG-SA  CAN-2002-1350  bgp X - - - see past OpenPKG-SA  CAN-2003-0108  isakmp X - - - see past OpenPKG-SA  depth X X X - (*) CAN-2003-0989  isakmp X X X - updates CAN-2003-0108-isakmp CAN-2003-1029  l2tp X X - - CAN-2004-0055  radius X X X X CAN-2004-0057  isakmp X X X X (*) the vendor code fix for CAN-2003-0108 had two other unrelated code changes piggybacked. We removed the cosmetics (constify) and extracted an enhancement (depth). Please check whether you are affected by running "
/bin/rpm -q tcpdump". If you have the "tcpdump" package installed and its version is affected (see above), we recommend that you immediately upgrade it (see Solution).  Solution: Select the updated source RPM appropriate for your OpenPKG release , fetch it from the OpenPKG FTP service  or a mirror location, verify its integrity , build a corresponding binary RPM from it  and update your OpenPKG installation by applying the binary RPM . 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 tcpdump-3.7.2-1.3.1.src.rpm ftp> bye $ /bin/rpm -v --checksig tcpdump-3.7.2-1.3.1.src.rpm $ /bin/rpm --rebuild tcpdump-3.7.2-1.3.1.src.rpm $ su - # /bin/rpm -Fvh /RPM/PKG/tcpdump-3.7.2-1.3.1.*.rpm ________________________________________________________________________ References:  http://www.tcpdump.org/  http://www.openpkg.org/security/OpenPKG-SA-2003.014-tcpdump.html  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-0380  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-1350  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0108  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0989  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-1029  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0055  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0057  http://www.openpkg.org/tutorial.html#regular-source  http://www.openpkg.org/tutorial.html#regular-binary  ftp://ftp.openpkg.org/release/1.2/UPD/tcpdump-3.7.1-1.2.2.src.rpm  ftp://ftp.openpkg.org/release/1.3/UPD/tcpdump-3.7.2-1.3.1.src.rpm  ftp://ftp.openpkg.org/release/1.2/UPD/  ftp://ftp.openpkg.org/release/1.3/UPD/  http://www.openpkg.org/security.html#signature ________________________________________________________________________ For security reasons, this advisory was digitally signed with the OpenPGP public key "OpenPKG "(ID 63C4CB9F) of the OpenPKG project which you can retrieve from http://pgp.openpkg.org and hkp://pgp.openpkg.org.
