Packet Storm Security Advisories
PRE-CERT Security Advisory - The Linux kernel contains a vulnerability in the driver for HFS plus file systems that may be exploited for code execution or privilege escalation. A specially-crafted HFS plus filesystem can cause a buffer overflow via the memcpy() call of hfs_bnode_read() (in fs/hfsplus/bnode.c).

Red Hat Security Advisory 2012-0571-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way the Linux kernel's journal_unmap_buffer() function handled buffer head states. On systems that have an ext4 file system with a journal mounted, a local, unprivileged user could use this flaw to cause a denial of service. A flaw was found in the way the KVM_CREATE_IRQCHIP ioctl was handled. Calling this ioctl when at least one virtual CPU already existed could lead to a NULL pointer dereference later when the VCPU is scheduled to run. A local, unprivileged user on a KVM host could use this flaw to crash the host.

Hack a Day
The latest version of the Linux kernel was just released on Sunday, and there’s a little bonus which we think is worth considering. It seems that many changes from Android made their way into version 3.3 of the Linux kernel. This may not sound like much, but it’s a great example of the power of [...]

Ubuntu Security Notice 1394-1 - Aristide Fattori and Roberto Paleari reported a flaw in the Linux kernel's handling of IPv4 icmp packets. A remote user could exploit this to cause a denial of service. Vegard Nossum discovered a leak in the kernel's inotify_init() system call. A local, unprivileged user could exploit this to cause a denial of service. An error was discovered in the kernel's handling of CUSE (Character device in Userspace). A local attacker might exploit this flaw to escalate privilege, if access to /dev/cuse has been modified to allow non-root users. Various other issues were also addressed.

[Fernando] wrote in to share his take on building a logic analyzer. He’s using the parallel port to capture data and feed it to the display software of your choice. The method depends on a custom kernel which alters the way the parallel port works. The kernel he compiled includes a method of intercepting the [...]

Red Hat Security Advisory 2012-0152-03 - The kexec-tools package contains the /sbin/kexec binary and utilities that together form the user-space component of the kernel's kexec feature. The /sbin/kexec binary facilitates a new kernel to boot using the kernel's kexec feature either on a normal or a panic reboot. The kexec fastboot mechanism allows booting a Linux kernel from the context of an already running kernel. Kdump used the SSH "StrictHostKeyChecking=no" option when dumping to SSH targets, causing the target kdump server's SSH host key not to be checked. This could make it easier for a man-in-the-middle attacker on the local network to impersonate the kdump SSH target server and possibly gain access to sensitive information in the vmcore dumps.

Red Hat Security Advisory 2011-1419-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. The way IPv4 and IPv6 protocol sequence numbers and fragment IDs were generated could allow a man-in-the-middle attacker to inject packets and possibly hijack connections. Protocol sequence numbers and fragment IDs are now more random. A flaw was found in the Linux kernel's clock implementation on 32-bit, SMP systems. A local, unprivileged user could use this flaw to cause a divide error fault, resulting in a denial of service.
