Descriptions
The ip6_find_1stfragopt function in net/ipv6/output_core.c in the Linux kernel through 4.12.3 allows local users to cause a denial of service (integer overflow and infinite loop) by leveraging the ability to open a raw socket.
La función ip6_find_1stfragopt en el archivo net/ipv6/output_core.c en el kernel de Linux hasta la versión 4.12.3, permite a los usuarios locales causar una denegación de servicio (desbordamiento de enteros y bucle infinito) mediante la explotación de la capacidad de abrir un socket sin procesar.
An integer overflow vulnerability in ip6_find_1stfragopt() function was found. A local attacker that has privileges (of CAP_NET_RAW) to open raw socket can cause an infinite loop inside the ip6_find_1stfragopt() function.
