CVE-2014-8769
Description
From CVE.org
tcpdump 3.8 through 4.6.2 might allow remote attackers to obtain sensitive information from memory or cause a denial of service (packet loss or segmentation fault) via a crafted Ad hoc On-Demand Distance Vector (AODV) packet, which triggers an out-of-bounds memory access.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
