Summary
Red Hat Security Advisory: : Updated Ethereal packages fix security issues
Severity
Low
Notes
Topic: Updated Ethereal packages that fix two security vulnerabilities are now available.
Details: Ethereal is a program for monitoring network traffic. Two security issues have been found that affect Ethereal. By exploiting these issues it may be possible to make Ethereal crash by injecting an intentionally malformed packet onto the wire or by convincing someone to read a malformed packet trace file. It is not known if these issues could allow arbitrary code execution. The SMB dissector in Ethereal before 0.10.0 allows remote attackers to cause a denial of service via a malformed SMB packet that triggers a segmentation fault during processing of Selected packets. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-1012 to this issue. The Q.931 dissector in Ethereal before 0.10.0 allows remote attackers to cause a denial of service (crash) via a malformed Q.931, which triggers a null dereference. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-1013 to this issue. Users of Ethereal should update to these erratum packages containing Ethereal version 0.10.0, which is not vulnerable to these issues.

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.
