Description Jan Lieskovsky 2013-06-10 12:02:22 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2013-4074 to the following vulnerability:

The dissect_capwap_data function in epan/dissectors/packet-capwap.c in the CAPWAP dissector in Wireshark 1.6.x before 1.6.16 and 1.8.x before 1.8.8 incorrectly uses a -1 data value to represent an error condition, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

The version of wireshark shipped with Red Hat Enterprise Linux 5 and 6 does not have support for Control And Provisioning of Wireless Access Points (CAPWAP) Protocol. Therefore this flaw does not affect these versions.
