Insight

Insight

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security fixes: * a NULL pointer dereference flaw was found in the sctp_rcv_ootb() function in the Linux kernel Stream Control Transmission Protocol (SCTP) implementation. A remote attacker could send a specially-crafted SCTP packet to a target system, resulting in a denial of service. (CVE-2010-0008, Important) * a missing boundary check was found in the do_move_pages() function in the memory migration functionality in the Linux kernel. A local user could use this flaw to cause a local denial of service or an information leak. (CVE-2010-0415, Important) * a NULL pointer dereference flaw was found in the ip6_dst_lookup_tail() function in the Linux kernel. An attacker on the local network could trigger this flaw by sending IPv6 traffic to a target system, leading to a system crash (kernel OOPS) if dst->neighbour is NULL on the target system when receiving an IPv6 packet. (CVE-2010-0437, Important) * a NULL pointer dereference flaw was found in the ext4 file system code in the Linux kernel. A local attacker could use this flaw to trigger a local denial of service by mounting a specially-crafted, journal-less ext4 file system, if that file system forced an EROFS error. (CVE-2009-4308, Moderate) * an information leak was found in the print_fatal_signal() implementation in the Linux kernel. When '/proc/sys/kernel/print-fatal-signals' is set to 1 (the default value is 0), memory that is reachable by the kernel could be leaked to user-space. This issue could also result in a system crash. Note that this flaw only affected the i386 architecture. (CVE-2010-0003, Moderate) * missing capability checks were found in the ebtables implementation, used for creating an Ethernet bridge firewall. This could allow a local, unprivileged user to bypass intended capability restrictions and modify ebtables rules. (CVE-2010-0007, Low) Bug fixes: * a bug prevented Wake on LAN (WoL) being enabled on certain Intel hardware. (BZ#543449) * a race issue in the Journaling Block Device. (BZ#553132) * programs compiled on x86, and that also call sched_rr_get_interval(), were silently corrupted when run on 64-bit systems. (BZ#557684) * the RHSA-2010:0019 update introduced a regression, preventing WoL from working for network devices using the e1000e driver. (BZ#559335) * adding a bonding interface in mode balance-alb to a bridge was not functional. (BZ#560588) * some KVM (Kernel-based Virtual Machine) guests ...
