-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2014:201 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : kernel Date : October 21, 2014 Affected: Business Server 1.0 _______________________________________________________________________ Problem Description: Multiple vulnerabilities has been found and corrected in the Linux kernel: The try_to_unmap_cluster function in mm/rmap.c in the Linux kernel before 3.14.3 does not properly consider which pages must be locked, which allows local users to cause a denial of service (system crash) by triggering a memory-usage pattern that requires removal of page-table mappings (CVE-2014-3122). Multiple stack-based buffer overflows in the magicmouse_raw_event function in drivers/hid/hid-magicmouse.c in the Magic Mouse HID driver in the Linux kernel through 3.16.3 allow physically proximate attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a crafted device that provides a large amount of (1) EHCI or (2) XHCI data associated with an event (CVE-2014-3181). Array index error in the logi_dj_raw_event function in drivers/hid/hid-logitech-dj.c in the Linux kernel before 3.16.2 allows physically proximate attackers to execute arbitrary code or cause a denial of service (invalid kfree) via a crafted device that provides a malformed REPORT_TYPE_NOTIF_DEVICE_UNPAIRED value (CVE-2014-3182). The report_fixup functions in the HID subsystem in the Linux kernel before 3.16.2 might allow physically proximate attackers to cause a denial of service (out-of-bounds write) via a crafted device that provides a small report descriptor, related to (1) drivers/hid/hid-cherry.c, (2) drivers/hid/hid-kye.c, (3) drivers/hid/hid-lg.c, (4) drivers/hid/hid-monterey.c, (5) drivers/hid/hid-petalynx.c, and (6) drivers/hid/hid-sunplus.c (CVE-2014-3184). Multiple buffer overflows in the command_port_read_callback function in drivers/usb/serial/whiteheat.c in the Whiteheat USB Serial Driver in the Linux kernel before 3.16.2 allow physically proximate attackers to execute arbitrary code or cause a denial of service (memory corruption and system crash) via a crafted device that provides a large amount of (1) EHCI or (2) XHCI data associated with a bulk response (CVE-2014-3185). Buffer overflow in the picolcd_raw_event function in devices/hid/hid-picolcd_core.c in the PicoLCD HID device driver in the Linux kernel through 3.16.3, as used in Android on Nexus 7 devices, allows physically proximate attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a crafted device that sends a large report (CVE-2014-3186). arch/s390/kernel/ptrace.c in the Linux kernel before 3.15.8 on the s390 platform does not properly restrict address-space control operations in PTRACE_POKEUSR_AREA requests, which allows local users to obtain read and write access to kernel memory locations, and consequently gain privileges, via a crafted application that makes a ptrace system call (CVE-2014-3534). The kvm_iommu_map_pages function in virt/kvm/iommu.c in the Linux kernel through 3.16.1 miscalculates the number of pages during the handling of a mapping failure, which allows guest OS users to (1) cause a denial of service (host OS memory corruption) or possibly have unspecified other impact by triggering a large gfn value or (2) cause a denial of service (host OS memory consumption) by triggering a small gfn value that leads to permanently pinned pages (CVE-2014-3601). The sctp_assoc_update function in net/sctp/associola.c in the Linux kernel through 3.15.8, when SCTP authentication is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by starting to establish an association between two endpoints immediately after an exchange of INIT and INIT ACK chunks to establish an earlier association between these endpoints in the opposite direction (CVE-2014-5077). The do_remount function in fs/namespace.c in the Linux kernel through 3.16.1 does not maintain the MNT_LOCK_READONLY bit across a remount of a bind mount, which allows local users to bypass an intended read-only restriction and defeat certain sandbox protection mechanisms via a mount -o remount command within a user namespace (CVE-2014-5206). Stack consumption vulnerability in the parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel through 3.16.1 allows local users to cause a denial of service (uncontrolled recursion, and system crash or reboot) via a crafted iso9660 image with a CL entry referring to a directory entry that has a CL entry (CVE-2014-5471). The parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel through 3.16.1 allows local users to cause a denial of service (unkillable mount process) via a crafted iso9660 image with a self-referential CL entry (CVE-2014-5472). The __udf_read_inode function in fs/udf/inode.c in the Linux kernel through 3.16.3 does not restrict the amount of ICB indirection, which allows physically proximate attackers to cause a denial of service (infinite loop or stack consumption) via a UDF filesystem with a crafted inode (CVE-2014-6410). The do_umount function in fs/namespace.c in the Linux kernel through 3.17 does not require the CAP_SYS_ADMIN capability for do_remount_sb calls that change the root filesystem to read-only, which allows local users to cause a denial of service (loss of writability) by making certain unshare system calls, clearing the / MNT_LOCKED flag, and making an MNT_FORCE umount system call (CVE-2014-7975). The updated packages provides a solution for these security issues. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3122 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3181 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3182 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3184 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3185 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3186 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3534 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3601 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-5077 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-5206 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-5471 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-5472 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-6410 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-7975 _______________________________________________________________________ Updated Packages: Mandriva Business Server 1/X86_64: 706f1d3e028f5c472fae4cd5647fdf2c mbs1/x86_64/cpupower-3.4.104-1.1.mbs1.x86_64.rpm 0197c7237e6de17e12ed06e19a24a1f3 mbs1/x86_64/kernel-firmware-3.4.104-1.1.mbs1.noarch.rpm 02105e0da2b67be743fc2fb09e5cb7bd mbs1/x86_64/kernel-headers-3.4.104-1.1.mbs1.x86_64.rpm c7c658c1fb347718937a094224ac8253 mbs1/x86_64/kernel-server-3.4.104-1.1.mbs1.x86_64.rpm 72d8fab7697670cbc0e133f60c5c9106 mbs1/x86_64/kernel-server-devel-3.4.104-1.1.mbs1.x86_64.rpm e4352dee03821deb157454ca1ee5c085 mbs1/x86_64/kernel-source-3.4.104-1.mbs1.noarch.rpm c7c93d2471a205797fa628405cee250b mbs1/x86_64/lib64cpupower0-3.4.104-1.1.mbs1.x86_64.rpm 09c3ce0b324c9f077a25435f2fadfa54 mbs1/x86_64/lib64cpupower-devel-3.4.104-1.1.mbs1.x86_64.rpm 46e6313a2a74f0c6e5704a84ad6a9350 mbs1/x86_64/perf-3.4.104-1.1.mbs1.x86_64.rpm 6ba4c2613b0c731f74e349feb08aa7ed mbs1/SRPMS/cpupower-3.4.104-1.1.mbs1.src.rpm fb946993475cccf1445d9dc5d03578f0 mbs1/SRPMS/kernel-firmware-3.4.104-1.1.mbs1.src.rpm ecd7276d9cbe6d58d0ff72437e942155 mbs1/SRPMS/kernel-headers-3.4.104-1.1.mbs1.src.rpm e47de9f04bd8c4fa65cd7064d7162beb mbs1/SRPMS/kernel-server-3.4.104-1.1.mbs1.src.rpm 0904c9462ac38c922acb9163c30733ff mbs1/SRPMS/kernel-source-3.4.104-1.mbs1.src.rpm 94ce7abe8ff4987551f0570443855114 mbs1/SRPMS/perf-3.4.104-1.1.mbs1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
