Description

The remote Cisco Wireless LAN Controller (WLC) is affected by one or more of the following vulnerabilities :

  • Errors exist related to the handling of specially crafted ethernet 802.11 frames that could allow denial of service attacks. (CSCue87929, CSCuf80681)

  • An error exists related to the handling of WebAuth logins that could allow denial of service attacks. (CSCuf52361)

  • An error exists related to the unintended enabling of the HTTP administrative interface on Aironet access points due to flaws in the IOS code pushed to them by the controller. (CSCuf66202)

  • A memory over-read error exists related to IGMP handling that could allow denial of service attacks. (CSCuh33240)

  • An error exists related to the multicast listener discovery (MLD) service and malformed MLD version 2 message handling that could allow denial of service attacks. (CSCuh74233)
