Topic: Updated ethereal packages are available for Red Hat Powertools 6.2, 7, and 7.1. These packages are required for the Red Hat Security Advisory regarding applications linked against the old ucd-snmp libraries and also fix other security issues in ethereal. 2. Relevant releases/architectures: Red Hat Powertools 6.2 - alpha, i386 Red Hat Powertools 7.0 - alpha, i386 Red Hat Powertools 7.1 - alpha, i386 3. Problem description: Ethereal is a network traffic analyzer and monitor. The Red Hat Security Advisory for ucd-snmp included updated libraries. All applications linked against the old ucd-snmp libraries need to be updated. If you have updated your ucd-snmp package you must update the ethereal package as well. For all other third party applications possibly affected by the Red Hat Security Advisory for ucd-snmp, please contact the software vendor. This errata provides Ethereal version 0.9.6. Previous versions of Ethereal were found to contain a number of security issues: Buffer overflow in Ethereal 0.9.5 and earlier allows remote attackers to cause a denial of service or execute arbitrary code via the ISIS dissector. (CAN-2002-0834) Buffer overflows in Ethereal 0.9.4 and earlier allow remote attackers to cause a denial of service or execute arbitrary code via the BGP dissector or the WCP dissector. (CAN-2002-0821) Ethereal 0.9.4 and earlier allows remote attackers to cause a denial of service and possibly excecute arbitrary code via the SOCKS,=20 RSVP, AFS, or LMP dissectors, which can be caused to core dump. (CAN-2002-0822) Due to improper string and error handling in Ethereal's ASN.1 parser, it is possible for a malformed SNMP or LDAP packet to cause a memory allocation or buffer overrun error in Ethereal versions before 0.9.2. (CAN-2002-0013 CAN-2002-0012) The ASN.1 parser in Ethereal 0.9.2 and earlier allows remote attackers to cause a denial of service (crash) via a certain malformed packet, which causes Ethereal to allocate memory incorrectly, possibly due to zero-length fields. (CAN-2002-0353) The SMB dissector in Ethereal prior to version 0.9.2 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via malformed packets that cause Ethereal to dereference a NULL pointer. (CAN-2002-0401) A buffer overflow in X11 dissector in Ethereal before 0.9.4 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code while Ethereal is parsing keysyms. (CAN-2002-0402) The DNS dissector in Ethereal before 0.9.4 allows remote attackers to cause a denial of service (CPU consumption) via a malformed packet that causes Ethereal to enter an infinite loop. (CAN-2002-0403) A vulnerability in the GIOP dissector in Ethereal before 0.9.4 allows remote attackers to cause a denial of service (memory consumption). (CAN-2002-0404) 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs. Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5.
