Scientific Linux Security Update : kernel on SL5.x i386/x86_64

high Nessus Plugin ID 60749


The remote Scientific Linux host is missing one or more security updates.


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 experienced slow performance (and possibly a crash) after suspend/resume. (BZ#560640)

- on some systems, VF cannot be enabled in dom0.

- on systems with certain network cards, a system crash occurred after enabling GRO. (BZ#561417)

- for x86 KVM guests with pvclock enabled, the boot clocks were registered twice, possibly causing KVM to write data to a random memory area during the guest's life.

- serious performance degradation for 32-bit applications, that map (mmap) thousands of small files, when run on a 64-bit system. (BZ#562746)

- improved kexec/kdump handling. Previously, on some systems under heavy load, kexec/kdump was not functional. (BZ#562772)

- dom0 was unable to boot when using the Xen hypervisor on a system with a large number of logical CPUs.

- a fix for a bug that could potentially cause file system corruption. (BZ#564281)

- a bug caused infrequent cluster issues for users of GFS2. (BZ#564288)

- gfs2_delete_inode failed on read-only file systems.

The system must be rebooted for this update to take effect.
