Descriptions
The netfilter subsystem in the Linux kernel before 4.9 mishandles IPv6 reassembly, which allows local users to cause a denial of service (integer overflow, out-of-bounds write, and GPF) or possibly have unspecified other impact via a crafted application that makes socket, connect, and writev system calls, related to net/ipv6/netfilter/nf_conntrack_reasm.c and net/ipv6/netfilter/nf_defrag_ipv6_hooks.c.
El subsistema netfilter en el kernel de Linux en versiones anteriores a 4.9 no maneja adecuadamente reensamblaje IPv6, lo que permite a usuarios locales provocar una denegación de servicio (desbordamiento de entero, escritura fuera de límites y GPF) o posiblemente tener otro impacto no especificado a través de una aplicación manipulada que hace un socket, conecta y escribe llamadas al sistema, relacionado con net/ipv6/netfilter/nf_conntrack_reasm.c y net/ipv6/netfilter/nf_defrag_ipv6_hooks.c.
USN-3358-1 fixed vulnerabilities in the Linux kernel for Ubuntu 17.04. This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 17.04 for Ubuntu 16.04 LTS. Please note that this update changes the Linux HWE kernel to the 4.10 based kernel from Ubuntu 17.04, superseding the 4.8 based HWE kernel from Ubuntu 16.10. Ben Harris discovered that the Linux kernel would strip extended privilege attributes of files when performing a failed unprivileged system call. A local attacker could use this to cause a denial of service. Various other issues were also addressed.
