RHSA-2003_151

Vulnerability from csaf_redhat - Published: 2003-06-09 13:44 - Updated: 2024-11-21 22:44
Summary
Red Hat Security Advisory: tcpdump security update
Severity
Moderate
Notes
Topic: Updated tcpdump packages that fix an infinite loop vulnerability and drop privileges on startup are now available.
Details: Tcpdump is a command-line tool for monitoring network traffic. A vulnerability exists in tcpdump before 3.7.2 and is related to an inability to handle unknown RADIUS attributes properly. This vulnerability allows remote attackers to cause a denial of service (infinite loop). The Red Hat tcpdump packages advertise that, by default, tcpdump will drop privileges to user 'pcap'. Due to a compilation error this did not happen, and tcpdump would run as root unless the '-U' flag was specified. Users of tcpdump are advised to upgrade to these errata packages, which contain a patch correcting the RADIUS issue and are compiled so that by default tcpdump will drop privileges to the 'pcap' user.

  • 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.
