SCO Security Advisory
Subject: OpenLinux: Multiple vulnerabilities have reported in Ethereal 0.9.12 Advisory number: CSSA-2003-030.0 Issue date: 2003 November 07 Cross reference: sr883585 fz528203 erg712398 CAN-2003-0428 CAN-2003-0429 CAN-2003-0430 CAN-2003-0431 CAN-2003-0432 ______________________________________________________________________________
1. Problem Description
Multiple vulnerabilities have reported in Ethereal 0.9.12. Ethereal is a freely available network protocol analyzer for Microsoft Windows and multiple Unix-based operating systems. Ethereal versions 0.9.12 and earlier are vulnerable to multiple issues. The Vulnerabilities are: 1. The DCERPC dissector could try to allocate too much memory while trying to decode an NDR string. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the following name CAN-2003-0428 to this issue. 2. Bad IPv4 or IPv6 prefix lengths could cause an overflow in the OSI dissector. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the following name CAN-2003-0429 to this issue. 3. The SPNEGO dissector could segfault while parsing an invalid ASN.1 value. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the following name CAN-2003-0430 to this issue. 4. The tvb_get_nstringz0() routine incorrectly handled a zero- length buffer size. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the following name CAN-2003-0431 to this issue. 5. The BGP, WTP, DNS, 802.11, ISAKMP, WSP, CLNP, ISIS, and RMI dissectors handled strings improperly. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the following name CAN-2003-0432 to this issue. POTENTIAL IMPACT It may be possible to make Ethereal crash or run arbitrary code by injecting a purposefully malformed packet onto the wire, or by convincing someone to read a malformed packet trace file.
2. Vulnerable Supported Versions
System Package ------------------------------------------------------------------- OpenLinux 3.1.1 Server prior to ethereal-0.9.13-1.i386.rpm OpenLinux 3.1.1 Workstation prior to ethereal-0.9.13-1.i386.rpm
3. Solution
The proper solution is to install the latest packages. Many customers find it easier to use the Caldera System Updater, called cupdate (or kcupdate under the KDE environment), to update these packages rather than downloading and installing them by hand.
