glibc: Unbounded stack allocation in nan* functions

Multiple stack-based buffer overflows in the GNU C Library (aka glibc or libc6) before 2.23 allow context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long argument to the (1) nan, (2) nanf, or (3) nanl function.

xdelta: buffer overflow in main_get_appheader

Buffer overflow in the main_get_appheader function in xdelta3-main.h in xdelta3 before 3.0.9 allows remote attackers to execute arbitrary code via a crafted input file.

chromium-browser: csp bypass for serviceworker

The ServiceWorkerContainer::registerServiceWorkerImpl function in WebKit/Source/modules/serviceworkers/ServiceWorkerContainer.cpp in Blink, as used in Google Chrome before 51.0.2704.63, allows remote attackers to bypass the Content Security Policy (CSP) protection mechanism via a ServiceWorker registration.

libxml2: Heap-based buffer overread in htmlCurrentChar

The htmlCurrentChar function in libxml2 before 2.9.4, as used in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1, allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted XML document.

kernel: Kernel memory leakage to ethernet frames due to buffer overflow in ethernet drivers

The atl2_probe function in drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel through 4.5.2 incorrectly enables scatter/gather I/O, which allows remote attackers to obtain sensitive information from kernel memory by reading packet data.

curl: URL request injection vulnerability in parseurlandfillconn()

CRLF injection vulnerability in libcurl 6.0 through 7.x before 7.40.0, when using an HTTP proxy, allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via CRLF sequences in a URL.

libvirt: local denial of service in qemu/qemu_driver.c

The (1) qemuDomainMigratePerform and (2) qemuDomainMigrateFinish2 functions in qemu/qemu_driver.c in libvirt do not unlock the domain when an ACL check fails, which allow local users to cause a denial of service via unspecified vectors.

kernel: x86: espfix not working for 32-bit KVM paravirt guests

The paravirt_ops_setup function in arch/x86/kernel/kvm.c in the Linux kernel through 3.18 uses an improper paravirt_enabled setting for KVM guest kernels, which makes it easier for guest OS users to bypass the ASLR protection mechanism via a crafted application that reads a 16-bit value.

Double free vulnerability in the ssh_packet_kexinit function in kex.c in libssh 0.5.x and 0.6.x before 0.6.4 allows remote attackers to cause a denial of service via a crafted kexinit packet.

kernel: Stack overflow via ecryptfs and /proc/$pid/environ

The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the Linux kernel before 4.6.3 allows local users to gain privileges or cause a denial of service (stack memory consumption) via vectors involving crafted mmap calls for /proc pathnames, leading to recursive pagefault handling.

chromium-browser: use-after-free in Navigation

Use-after-free vulnerability in the RenderWidgetHostImpl::Destroy function in content/browser/renderer_host/render_widget_host_impl.cc in the Navigation implementation in Google Chrome before 49.0.2623.108 allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.

glibc: Unexpected closing of nss_files databases after lookups causes denial of service

DB_LOOKUP in nss_files/files-XXX.c in the Name Service Switch (NSS) in GNU C Library (aka glibc or libc6) 2.21 and earlier does not properly check if a file is open, which allows remote attackers to cause a denial of service (infinite loop) by performing a look-up on a database while iterating over it, which triggers the file pointer to be reset.

file: denial of service issue (resource consumption)

softmagic.c in file before 5.21 does not properly limit recursion, which allows remote attackers to cause a denial of service (CPU consumption or crash) via unspecified vectors.

LXD before 2.0.2 uses world-readable permissions for /var/lib/lxd/zfs.img when setting up a loop based ZFS pool, which allows local users to copy and read data from arbitrary containers via unspecified vectors.

file: multiple denial of service issues (resource consumption)

The ELF parser (readelf.c) in file before 5.21 allows remote attackers to cause a denial of service (CPU consumption or crash) via a large number of (1) program or (2) section headers or (3) invalid capabilities.

httpd: LuaAuthzProvider argument handling issue

mod_lua.c in the mod_lua module in the Apache HTTP Server 2.3.x and 2.4.x through 2.4.10 does not support an httpd configuration in which the same Lua authorization provider is used with different arguments within different contexts, which allows remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging multiple Require directives, as demonstrated by a configuration that specifies authorization for one group to access a certain directory, and authorization for a second group to access a second directory.

LXD before 2.0.2 does not properly set permissions when switching an unprivileged container into privileged mode, which allows local users to access arbitrary world readable paths in the container directory via unspecified vectors.

chromium-browser: buffer overflow in libANGLE

The Program::getUniformInternal function in Program.cpp in libANGLE, as used in Google Chrome before 49.0.2623.108, does not properly handle a certain data-type mismatch, which allows remote attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact via crafted shader stages.

OpenVPN 2.x before 2.0.11, 2.1.x, 2.2.x before 2.2.3, and 2.3.x before 2.3.6 allows remote authenticated users to cause a denial of service (server crash) via a small control channel packet.

ruby: REXML billion laughs attack via parameter entity expansion

The REXML parser in Ruby 1.9.x before 1.9.3-p550, 2.0.x before 2.0.0-p594, and 2.1.x before 2.1.4 allows remote attackers to cause a denial of service (memory consumption) via a crafted XML document, aka an XML Entity Expansion (XEE) attack.
