Description Agostino Sarubbo gentoo-dev 2017-07-12 07:35:40 UTC
CVE-2017-11108 (

tcpdump 4.9.0 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via crafted packet data. The crash occurs in the EXTRACT_16BITS function, called from the stp_print function for the Spanning Tree Protocol.

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
