Background ========== Ethereal is a feature rich network protocol analyzer. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-analyzer/ethereal < 0.10.11 >= 0.10.11 Description =========== There are numerous vulnerabilities in versions of Ethereal prior to 0.10.11, including: * The ANSI A and DHCP dissectors are vulnerable to format string vulnerabilities. * The DISTCC, FCELS, SIP, ISIS, CMIP, CMP, CMS, CRMF, ESS, OCSP, PKIX1Explitit, PKIX Qualified, X.509, Q.931, MEGACO, NCP, ISUP, TCAP and Presentation dissectors are vulnerable to buffer overflows. * The KINK, WSP, SMB Mailslot, H.245, MGCP, Q.931, RPC, GSM and SMB NETLOGON dissectors are vulnerable to pointer handling errors. * The LMP, KINK, MGCP, RSVP, SRVLOC, EIGRP, MEGACO, DLSw, NCP and L2TP dissectors are vulnerable to looping problems. * The Telnet and DHCP dissectors could abort. * The TZSP, Bittorrent, SMB, MGCP and ISUP dissectors could cause a segmentation fault. * The WSP, 802.3 Slow protocols, BER, SMB Mailslot, SMB, NDPS, IAX2, RADIUS, SMB PIPE, MRDISC and TCAP dissectors could throw assertions. * The DICOM, NDPS and ICEP dissectors are vulnerable to memory handling errors. * The GSM MAP, AIM, Fibre Channel,SRVLOC, NDPS, LDAP and NTLMSSP dissectors could terminate abnormallly. Impact ====== An attacker might be able to use these vulnerabilities to crash Ethereal and execute arbitrary code with the permissions of the user running Ethereal, which could be the root user. Workaround ========== There is no known workaround at this time. Resolution ========== All Ethereal users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.10.11" References ========== [ 1 ] Ethereal enpa-sa-00019 http://www.ethereal.com/appnotes/enpa-sa-00019.html [ 2 ] CAN-2005-1456 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1456 [ 3 ] CAN-2005-1457 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1457 [ 4 ] CAN-2005-1458 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1458 [ 5 ] CAN-2005-1459 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1459 [ 6 ] CAN-2005-1460 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1460 [ 7 ] CAN-2005-1461 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1461 [ 8 ] CAN-2005-1462 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1462 [ 9 ] CAN-2005-1463 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1463 [ 10 ] CAN-2005-1464 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1464 [ 11 ] CAN-2005-1465 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1465 [ 12 ] CAN-2005-1466 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1466 [ 13 ] CAN-2005-1467 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1467 [ 14 ] CAN-2005-1468 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1468 [ 15 ] CAN-2005-1469 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1469 [ 16 ] CAN-2005-1470 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-1470 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200505-03.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
