Título:	Conectiva Security Advisory CLA-2003:662
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory CLA-2003:662. Ethereal[1] is a powerful network traffic analyzer with a graphical usr interface (GUI). This update announcement addresses several vulnerabilities[2,3] in ethereal versions <= 0.9.12. These vulnerabilities can be exploited by an attacker who can insert crafted packets in the wire being monitored by ethereal or make an user open a trace file with such packets inside. Successful exploitation of these vulnerabilities can lead to denial of service conditions and/or remote execution of arbitrary code. The following vulnerabilities have been fixed: - Denial of Service (DoS) in the DCERPC dissector when trying to decode a NDR string[4] - Buffer overflow in the OSI dissector when decoding IPv4 or IPv6 prefixes[5] - Denial of Service (DoS) in the SPNEGO dissector when parsing an invalid ASN.1 value[6] - Memory handling error in the tvb_get_nstringz0() routine when handling a zero-length buffer size[7] - Handling string vulnerabilities in the BGP, WTP, DNS, 802.11, ISAKMP, WSP, CLNP, ISIS and RMI dissectors[8]. The Common Vulnerabilities and Exposures (CVE) project has assigned the names CAN-2003-04{28,29,30,31,32} to these issues, respectively. Solution: The apt tool can be used to perform RPM package upgrades by running 'apt-get update' followed by 'apt-get upgrade' http://www.ethereal.com http://www.ethereal.com/appnotes/enpa-sa-00010.html http://distro2.conectiva.com.br/bugzilla/show_bug.cgi?id=8687 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2003-0428 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2003-0429 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2003-0430 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2003-0431 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2003-0432 https://secure1.securityspace.com/smysecure/catid.html?in=CLA-2003:662 http://distro.conectiva.com.br/atualizacoes/index.php?id=a&anuncio=002003 Risk factor : Critical CVSS Score: 10.0
