Descriptions

The security_context_to_sid_core function in security/selinux/ss/services.c in the Linux kernel before 3.13.4 allows local users to cause a denial of service (system crash) by leveraging the CAP_MAC_ADMIN capability to set a zero-length security context.

La función security_context_to_sid_core en security/selinux/ss/services.c en el kernel de Linux anterior a 3.13.4 permite a usuarios locales causar una denegación de servicio (caída del sistema) mediante el aprovechamiento de la funcionalidad CAP_MAC_ADMIN para configurar un contexto de seguridad de longitud cero.

The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A denial of service flaw was found in the way the Linux kernel's IPv6 implementation processed IPv6 router advertisement packets. An attacker able to send a large number of RA packets to a target system could potentially use this flaw to crash the target system. A flaw was found in the way the Linux kernel's netfilter connection tracking implementation for Datagram Congestion Control Protocol packets used the skb_header_pointer() function. A remote attacker could use this flaw to send a specially crafted DCCP packet to crash the system or, potentially, escalate their privileges on the system.
