CVE-2011-1959  (opens in a new tab)
CWE-119  (opens in a new tab)

How to fix?

Upgrade wireshark to version 1.2.17, 1.4.7 or higher.

Overview

Affected versions of this package are vulnerable to Out-of-Bounds. The snoop_read function in wiretap/snoop.c in Wireshark 1.2.x before 1.2.17 and 1.4.x before 1.4.7 does not properly handle certain virtualizable buffers, which allows remote attackers to cause a denial of service (application crash) via a large length value in a snoop file that triggers a stack-based buffer over-read.
