Detail
A vulnerability in the DHCP implementation of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability occurs during the parsing of crafted DHCP packets. An attacker could exploit this vulnerability by sending crafted DHCP packets to an affected device that has the DHCP server or DHCP relay feature enabled. An exploit could allow the attacker to cause a reload of an affected device. Cisco has released free software updates that address this vulnerability. There are no workarounds to this vulnerability. This advisory is available at the following link: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20130925-dhcp Note: The September 25, 2013, Cisco IOS Software Security Advisory bundled publication includes eight Cisco Security Advisories. All advisories address vulnerabilities in Cisco IOS Software. Each Cisco IOS Software Security Advisory lists the Cisco IOS Software releases that correct the vulnerability or vulnerabilities detailed in the advisory as well as the Cisco IOS Software releases that correct all Cisco IOS Software vulnerabilities in the September 2013 bundled publication. Individual publication links are in "Cisco Event Response: Semiannual Cisco IOS Software Security Advisory Bundled Publication" at the following link: http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_sep13.html BEGIN PGP SIGNATURE Version: GnuPG/MacGPG2 v2.0.18 (Darwin) Comment: GPGTools - http://gpgtools.org iF4EAREIAAYFAlJC6Z0ACgkQUddfH3/BbToKcAD/Y0gUqLxw1mMs8yqeoREI7H7x /bU2ckuJKhhzJmmqpjEA/3ekjyVjTXoLRR9vQrYnAeJSE4opTRXYTlJtZesv4tIw =zzbX END PGP SIGNATURE _______________________________________________ cust-security-announce mailing list cust-security-announce@cisco.com To unsubscribe, send the command "unsubscribe" in the subject of your message to cust-security-announce-leave@cisco.com |
