xen: populate-on-demand balloon size inaccuracy can crash guests on x86

The (1) libxl_set_memory_target function in tools/libxl/libxl.c and (2) libxl__build_post function in tools/libxl/libxl_dom.c in Xen 3.4.x through 4.6.x do not properly calculate the balloon size when using the populate-on-demand (PoD) system, which allows local HVM guest users to cause a denial of service (guest crash) via unspecified vectors related to "heavy memory pressure."

The Web Dispatcher service in SAP HANA DB 1.00.73.00.389160 (NewDB100_REL) allows remote attackers to read web dispatcher and security trace files and possibly obtain passwords via unspecified vectors, aka SAP Security Note 2148854.

Cisco IOS before 15.1(1)SY on ASR 1000 devices, when Multicast Listener Discovery (MLD) tracking is enabled for IPv6, allows remote attackers to cause a denial of service (device reload) via crafted MLD packets, aka Bug ID CSCtz28544.

The DisplayTopKeywords function in plugins/Referrers/Controller.php in Piwik before 2.15.0 allows remote attackers to conduct PHP object injection attacks, conduct Server-Side Request Forgery (SSRF) attacks, and execute arbitrary PHP code via a crafted HTTP header.

The HTTPAuthentication implementation in CFNetwork in Apple iOS before 8.4 and OS X before 10.10.4 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via crafted credentials in a URL.

xen: Host crash when preempting a multicall on ARM

The hypercall_create_continuation function in arch/arm/domain.c in Xen 4.4.x through 4.6.x allows local guest users to cause a denial of service (host crash) via a preemptible hypercall to the multicall interface.

The Bluetooth HCI interface implementation in Apple OS X before 10.10.4 allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app.

The displayBlock function Template.php in Sensio Labs Twig before 1.20.0, when Sandbox mode is enabled, allows remote attackers to execute arbitrary code via the _self variable in a template.

QT Media Foundation in Apple QuickTime before 7.7.7 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted file, a different vulnerability than CVE-2015-3664 and CVE-2015-3665.

The default keybindings for wwm in LTSP Display Manager (ldm) 2.2.x before 2.2.7 allow remote attackers to execute arbitrary commands via the KP_RETURN keybinding, which launches a terminal window.

PC-EGG pWebManager before 3.3.10, and before 2.2.2 for PHP 4.x, allows remote authenticated users to execute arbitrary OS commands by leveraging the editor role.

libxpc in launchd in Apple OS X before 10.11 does not restrict the creation of processes for network connections, which allows remote attackers to cause a denial of service (resource consumption) by repeatedly connecting to the SSH port, a different vulnerability than CVE-2015-7761.

dovecot: DoS (daemon hang) when parsing invalid IMAP APPEND command parameters

The IMAP functionality in Dovecot before 2.2.2 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via invalid APPEND parameters.

Cross-site request forgery (CSRF) vulnerability in the Mail On Update plugin before 5.2.0 for WordPress allows remote attackers to hijack the authentication of administrators for requests that change the "List of alternative recipients" via the mailonupdate_mailto parameter in the mail-on-update page to wp-admin/options-general.php. NOTE: a third party claims that 5.2.1 and 5.2.2 are also vulnerable, but the issue might require a separate CVE identifier since this might reflect an incomplete fix.

lightdm before 1.0.9 does not properly close file descriptors before opening a child process, which allows local users to write to the lightdm log or have other unspecified impact.

gdk-pixbuf: Heap overflow and DoS vulnerability when scaling a TGA file

io-tga.c in gdk-pixbuf before 2.32.0 uses heap memory after its allocation failed, which allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) and possibly execute arbitrary code via a crafted Truevision TGA (TARGA) file.

Qemu: scsi: pvscsi: out-of-bounds access issue in pvsci_ring_init_msg/data routines

QEMU (aka Quick Emulator), when built with VMWARE PVSCSI paravirtual SCSI bus emulation support, allows local guest OS administrators to cause a denial of service (out-of-bounds array access) via vectors related to the (1) PVSCSI_CMD_SETUP_RINGS or (2) PVSCSI_CMD_SETUP_MSG_RING SCSI command.

The set_meta_data function in lib/cremefraiche.rb in the Creme Fraiche gem before 0.6.1 for Ruby allows remote attackers to execute arbitrary commands via shell metacharacters in the file name of an email attachment. NOTE: some of these details are obtained from third party information.

Multiple cross-site scripting (XSS) vulnerabilities in Gallery 3 before 3.0.7 allow remote attackers to inject arbitrary web script or HTML via the (1) movie title to modules/gallery/controllers/movies.php or (2) key variable to modules/gallery/views/error_admin.html.php.

Directory traversal vulnerability in apps/files_trashbin/index.php in ownCloud Server before 5.0.6 allows remote authenticated users to access arbitrary files via a .. (dot dot) in the dir parameter.
