ID de Prueba:	1.3.6.1.4.1.25623.1.0.51199
Categoría:	Red Hat Local Security Checks
Título:	RedHat Security Advisory RHSA-2003:033
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory RHSA-2003:033. Updated tcpdump, libpcap, and arpwatch packages are available to fix an incorrect bounds check when decoding BGP packets and a possible denial of service. Tcpdump is a command-line tool for monitoring network traffic. The BGP decoding routines in tcpdump before version 3.6.2 used incorrect bounds checking when copying data, which allows remote attackers to cause a denial of service and possibly execute arbitrary code (as the 'pcap' user). If a UDP packet from a radius port contains 0 at the second byte tcpdump gets stuck in a loop that generating an infinite stream of '#0#0#0#0#0'. This could be used as a denial of service. Users of tcpdump are advised to upgrade to these errata packages which contain patches to correct thes issues. Solution: Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date http://rhn.redhat.com/errata/RHSA-2003-033.html Risk factor : High CVSS Score: 7.5
