Vulnerability from csaf_redhat - Published: 2003-04-23 14:55 - Updated: 2025-11-21 17:25
Summary
Red Hat Security Advisory: : Updated tcpdump packages fix various vulnerabilities
Severity
Moderate
Notes
Topic: Updated tcpdump, libpcap, and arpwatch packages are available, fixing a number of vulnerabilities that could be used to cause a denial of service attack, or possibly execute arbitrary code.
Details: tcpdump is a command-line tool for monitoring network traffic. The BGP decoding routines in tcpdump before 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). 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. This causes tcpdump to generate data within an infinite loop. A vulnerability in tcpdump before 3.7.2 is related to an inability to handle unknown RADIUS attributes properly, and allows remote attackers to cause a denial of service (infinite loop). The ISAKMP parser in tcpdump 3.6 through 3.7.1 allows remote attackers to cause a denial of service (CPU consumption) via a malformed ISAKMP packet to UDP port 500, causing tcpdump to enter an infinite loop. Users of tcpdump are advised to upgrade to these errata packages, which contain patches to correct these issues.

CVE-2002-1350

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).

CVE-2003-0093

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.

Affected products
Fixed 4 products, the same list as for CVE-2002-1350
CVE-2003-0108

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.

Affected products
Fixed 4 products, the same list as for CVE-2002-1350
Threats
Impact Low
CVE-2003-0145

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.

Affected products
Fixed 4 products, the same list as for CVE-2002-1350

Taxonomy of the tags.




Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Sightings

Author Source Type Date Other

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

    Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
