Descriptions

The NAT implementation in Cisco IOS 12.1 through 12.4 and 15.0 through 15.1, and IOS XE 3.1.xSG, allows remote attackers to cause a denial of service (device reload or hang) via malformed NetMeeting Directory (aka Internet Locator Service or ILS) LDAP traffic, aka Bug ID CSCtd10712.

La implementación de NAT en Cisco IOS v12.1 a v12.4 y v15.0 a v15.1, y en Cisco IOS XE v3.1.xSG, permite a atacantes remotos causar una denegación de servicio (reinicio o bloqueo del dispositivo) a través de tráfico LDAP mal formado de Directorio de NetMeeting (también conocido como Internet Locator Service o ILS). Se trata de un problema también conocido como Bug ID CSCtd10712.

The Cisco IOS Software network address translation (NAT) feature contains multiple denial of service (DoS) vulnerabilities in the translation of multiple protocols. Cisco has released free software updates that address these vulnerabilities.
