CVE-2011-2175

Status Candidate

Overview

Integer underflow in the visual_read function in wiretap/visual.c in Wireshark 1.2.x before 1.2.17 and 1.4.x before 1.4.7 allows remote attackers to cause a denial of service (application crash) via a malformed Visual Networks file that triggers a heap-based buffer over-read.

Red Hat Security Advisory 2013-0125-01

Red Hat Security Advisory 2013-0125-01 - Wireshark, previously known as Ethereal, is a network protocol analyzer. It is used to capture and browse the traffic running on a computer network. A heap-based buffer overflow flaw was found in the way Wireshark handled Endace ERF capture files. If Wireshark opened a specially-crafted ERF capture file, it could crash or, possibly, execute arbitrary code as the user running Wireshark. Several denial of service flaws were found in Wireshark. Wireshark could crash or stop responding if it read a malformed packet off a network, or opened a malicious dump file.
