The kernel packages contain the Linux kernel, the core of any Linux operating system.
Security fixes :
The maximum file offset handling for ext4 file systems could allow a local, unprivileged user to cause a denial of service. (CVE-2011-2695, Important)
IPv6 fragment identification value generation could allow a remote attacker to disrupt a target system’s networking, preventing legitimate users from accessing its services. (CVE-2011-2699, Important)
A malicious CIFS (Common Internet File System) 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. (CVE-2011-3191, Important)
A local attacker could use mount.ecryptfs_private to mount (and then access) a directory they would otherwise not have access to. Note: To correct this issue, a ecryptfs-utils update must also be installed.
(CVE-2011-1833, Moderate)
A flaw in the taskstats subsystem could allow a local, unprivileged user to cause excessive CPU time and memory use. (CVE-2011-2484, Moderate)
Mapping expansion handling could allow a local, unprivileged user to cause a denial of service.
(CVE-2011-2496, Moderate)
GRO (Generic Receive Offload) fields could be left in an inconsistent state. An attacker on the local network could use this flaw to cause a denial of service. GRO is enabled by default in all network drivers that support it. (CVE-2011-2723, Moderate)
A previous update introduced a regression in the Ethernet bridge implementation. If a system had an interface in a bridge, and an attacker on the local network could send packets to that interface, they could cause a denial of service on that system. Xen hypervisor and KVM (Kernel-based Virtual Machine) hosts often deploy bridge interfaces. (CVE-2011-2942, Moderate)
A flaw in the Xen hypervisor IOMMU error handling implementation could allow a privileged guest user, within a guest operating system that has direct control of a PCI device, to cause performance degradation on the host and possibly cause it to hang. (CVE-2011-3131, Moderate)
IPv4 and IPv6 protocol sequence number and fragment ID generation could allow a man-in-the-middle attacker to inject packets and possibly hijack connections. Protocol sequence number and fragment IDs are now more random.
(CVE-2011-3188, Moderate)
A flaw in the kernel’s clock implementation could allow a local, unprivileged user to cause a denial of service.
(CVE-2011-3209, Moderate)
Non-member VLAN (virtual LAN) packet handling for interfaces in promiscuous mode and also using the be2net driver could allow an attacker on the local network to cause a denial of service. (CVE-2011-3347, Moderate)
A flaw in the auerswald USB driver could allow a local, unprivileged user to cause a denial of service or escalate their privileges by inserting a specially crafted USB device. (CVE-2009-4067, Low)
A flaw in the Trusted Platform Module (TPM) implementation could allow a local, unprivileged user to leak information to user space. (CVE-2011-1160, Low)
A local, unprivileged user could possibly mount a CIFS share that requires authentication without knowing the correct password if the mount was already mounted by another local user. (CVE-2011-1585, Low)
