Descriptions
net/packet/af_packet.c in the Linux kernel before 2.6.39.3 does not properly restrict user-space access to certain packet data structures associated with VLAN Tag Control Information, which allows local users to obtain potentially sensitive information via a crafted application.
net/packet/af_packet.c en el kernel de Linux antes de v2.6.39.3 no restringe adecuadamente el acceso al espacio de usuario a ciertas estructuras de paquetes de datos asociados VLAN Tag Control Information, lo que permite a usuarios locales obtener información sensible a través de una aplicación modificada.
The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A malicious CIFS server could send a specially-crafted response to a directory read request that would result in a denial of service or privilege escalation on a system that has a CIFS share mounted. The way fragmented IPv6 UDP datagrams over the bridge with UDP Fragmentation Offload functionality on were handled could allow a remote attacker to cause a denial of service.
