RHSA-2003_032
Vulnerability from csaf_redhat - Published: 2003-04-23 14:55 - Updated: 2024-11-21 22:37The BGP decoding routines in tcpdump 3.6.x before 3.7 do not properly copy data, which allows remote attackers to cause a denial of service (application crash).
The RADIUS decoder in tcpdump 3.6.2 and earlier allows remote attackers to cause a denial of service (crash) via an invalid RADIUS packet with a header length field of 0, which causes tcpdump to generate data within an infinite loop.
isakmp_sub_print in tcpdump 3.6 through 3.7.1 allows remote attackers to cause a denial of service (CPU consumption) via a certain malformed ISAKMP packet to UDP port 500, which causes tcpdump to enter an infinite loop.
Unknown vulnerability in tcpdump before 3.7.2 related to an inability to "Handle unknown RADIUS attributes properly," allows remote attackers to cause a denial of service (infinite loop), a different vulnerability than CAN-2003-0093.

Vulnerability from csaf_redhat - Published: 2003-02-26 15:17 - Updated: 2025-11-21 17:25The BGP decoding routines in tcpdump 3.6.x before 3.7 do not properly copy data, which allows remote attackers to cause a denial of service (application crash).
The RADIUS decoder in tcpdump 3.6.2 and earlier allows remote attackers to cause a denial of service (crash) via an invalid RADIUS packet with a header length field of 0, which causes tcpdump to generate data within an infinite loop.

Vulnerability from csaf_redhat - Published: 2003-04-23 14:55 - Updated: 2025-11-21 17:25The BGP decoding routines in tcpdump 3.6.x before 3.7 do not properly copy data, which allows remote attackers to cause a denial of service (application crash).
The RADIUS decoder in tcpdump 3.6.2 and earlier allows remote attackers to cause a denial of service (crash) via an invalid RADIUS packet with a header length field of 0, which causes tcpdump to generate data within an infinite loop.
isakmp_sub_print in tcpdump 3.6 through 3.7.1 allows remote attackers to cause a denial of service (CPU consumption) via a certain malformed ISAKMP packet to UDP port 500, which causes tcpdump to enter an infinite loop.
Unknown vulnerability in tcpdump before 3.7.2 related to an inability to "Handle unknown RADIUS attributes properly," allows remote attackers to cause a denial of service (infinite loop), a different vulnerability than CAN-2003-0093.

RHSA-2003_214
Vulnerability from csaf_redhat - Published: 2003-06-30 16:10 - Updated: 2024-11-21 22:45Buffer overflow in tcpdump 3.6.2 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary code via an NFS packet.
The BGP decoding routines in tcpdump 3.6.x before 3.7 do not properly copy data, which allows remote attackers to cause a denial of service (application crash).
The RADIUS decoder in tcpdump 3.6.2 and earlier allows remote attackers to cause a denial of service (crash) via an invalid RADIUS packet with a header length field of 0, which causes tcpdump to generate data within an infinite loop.
isakmp_sub_print in tcpdump 3.6 through 3.7.1 allows remote attackers to cause a denial of service (CPU consumption) via a certain malformed ISAKMP packet to UDP port 500, which causes tcpdump to enter an infinite loop.
Unknown vulnerability in tcpdump before 3.7.2 related to an inability to "Handle unknown RADIUS attributes properly," allows remote attackers to cause a denial of service (infinite loop), a different vulnerability than CAN-2003-0093.
tcpdump does not properly drop privileges to the pcap user when starting up.

Due to a compilation error this did not\nhappen, and tcpdump would run as root unless the \u0027-U\u0027 flag was specified.\n\nUsers of tcpdump are advised to upgrade to these errata packages, which\nare compiled so that by default tcpdump will drop privileges to the\n\u0027pcap\u0027 user.\n\nThe BGP decoding routines in tcpdump before 3.6.2 used incorrect bounds\nchecking when copying data, which allows remote attackers to cause a denial\nof service and possibly execute arbitrary code (as the \u0027pcap\u0027 user).\n\nThe RADIUS decoder in tcpdump 3.6.2 and earlier allows remote attackers to\ncause a denial of service (crash) via an invalid RADIUS packet with a\nheader length field of 0. This causes tcpdump to generate data within an\ninfinite loop.\n\nA vulnerability in tcpdump before 3.7.2 is related to an inability to\nhandle unknown RADIUS attributes properly, and allows remote attackers to\ncause a denial of service (infinite loop).\n\nThe ISAKMP parser in tcpdump 3.6 through 3.7.1 allows remote attackers to\ncause a denial of service (CPU consumption) via a malformed ISAKMP packet\nto UDP port 500, causing tcpdump to enter an infinite loop.\n\nVersions of tcpdump up to and including 3.6.2 have a buffer overflow that\ncan be triggered when tracing the network by a bad NFS packet. This issue\nwas found by David Woodhouse of Red Hat.\n\nUsers of tcpdump are advised to upgrade to these errata packages, which\ncontain patches to correct these issues.",

RHSA-2003:214
Vulnerability from csaf_redhat - Published: 2003-06-30 16:10 - Updated: 2025-11-21 17:26Buffer overflow in tcpdump 3.6.2 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary code via an NFS packet.
The BGP decoding routines in tcpdump 3.6.x before 3.7 do not properly copy data, which allows remote attackers to cause a denial of service (application crash).
The RADIUS decoder in tcpdump 3.6.2 and earlier allows remote attackers to cause a denial of service (crash) via an invalid RADIUS packet with a header length field of 0, which causes tcpdump to generate data within an infinite loop.
isakmp_sub_print in tcpdump 3.6 through 3.7.1 allows remote attackers to cause a denial of service (CPU consumption) via a certain malformed ISAKMP packet to UDP port 500, which causes tcpdump to enter an infinite loop.
Unknown vulnerability in tcpdump before 3.7.2 related to an inability to "Handle unknown RADIUS attributes properly," allows remote attackers to cause a denial of service (infinite loop), a different vulnerability than CAN-2003-0093.
tcpdump does not properly drop privileges to the pcap user when starting up.

Due to a compilation error this did not\nhappen, and tcpdump would run as root unless the \u0027-U\u0027 flag was specified.\n\nUsers of tcpdump are advised to upgrade to these errata packages, which\nare compiled so that by default tcpdump will drop privileges to the\n\u0027pcap\u0027 user.\n\nThe BGP decoding routines in tcpdump before 3.6.2 used incorrect bounds\nchecking when copying data, which allows remote attackers to cause a denial\nof service and possibly execute arbitrary code (as the \u0027pcap\u0027 user).\n\nThe RADIUS decoder in tcpdump 3.6.2 and earlier allows remote attackers to\ncause a denial of service (crash) via an invalid RADIUS packet with a\nheader length field of 0. This causes tcpdump to generate data within an\ninfinite loop.\n\nA vulnerability in tcpdump before 3.7.2 is related to an inability to\nhandle unknown RADIUS attributes properly, and allows remote attackers to\ncause a denial of service (infinite loop).\n\nThe ISAKMP parser in tcpdump 3.6 through 3.7.1 allows remote attackers to\ncause a denial of service (CPU consumption) via a malformed ISAKMP packet\nto UDP port 500, causing tcpdump to enter an infinite loop.\n\nVersions of tcpdump up to and including 3.6.2 have a buffer overflow that\ncan be triggered when tracing the network by a bad NFS packet. This issue\nwas found by David Woodhouse of Red Hat.\n\nUsers of tcpdump are advised to upgrade to these errata packages, which\ncontain patches to correct these issues.",
