CVE-2013-4930: Input Validation
First published: Mon Jul 29 2013(Updated: )
The dissect_dvbci_tpdu_hdr function in epan/dissectors/packet-dvbci.c in the DVB-CI dissector in Wireshark 1.8.x before 1.8.9 and 1.10.x before 1.10.1 does not validate a certain length value before decrementing it, which allows remote attackers to cause a denial of service (assertion failure and application exit) via a crafted packet.
