73e79f50856da66b94dc300dcf75b8e4967914b79209768459dcab2e0db44614Ubuntu Security Notice 2227-1 - A flaw was discovered in the Linux kernel's pseudo tty (pty) device. An unprivileged user could exploit this flaw to cause a denial of service (system crash) or potentially gain administrator privileges. Matthew Daley reported an information leak in the floppy disk driver of the Linux kernel. An unprivileged local user could exploit this flaw to obtain potentially sensitive information from kernel memory. Various other issues were also addressed.
030f8dbdef1c111fe4bbe4103734f72cb888f3ba4144f7241099df3eede3cb21Ubuntu Security Notice 2221-1 - Matthew Daley reported an information leak in the floppy disk driver of the Linux kernel. An unprivileged local user could exploit this flaw to obtain potentially sensitive information from kernel memory. Matthew Daley reported a flaw in the handling of ioctl commands by the floppy disk driver in the Linux kernel. An unprivileged local user could exploit this flaw to gain administrative privileges if the floppy disk module is loaded. Various other issues were also addressed.
5616975f2fb4dd39c84f62c8002d7351e1f5dddc09b837aabc10d511eb920b67Red Hat Security Advisory 2014-0439-01 - 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.

A guest OS user could exploit this flaw to execute arbitrary code on the host OS. Al Viro discovered an error in how CIFS in the Linux kernel handles uncached write operations. An unprivileged local user could exploit this flaw to cause a denial of service (system crash), obtain sensitive information from kernel memory, or possibly gain privileges. Various other issues were also addressed.
