Red Hat Security Advisory 2011-1465-01
Posted Nov 23, 2011
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2011-1465-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. IPv6 fragment identification value generation could allow a remote attacker to disrupt a target system's networking, preventing legitimate users from accessing its services. A signedness issue was found in the Linux kernel's CIFS implementation. 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.
