chromium-browser: various security fixes in Chrome 40.0.2214.111

Multiple unspecified vulnerabilities in Google Chrome before 40.0.2214.111 on Windows, OS X, and Linux and before 40.0.2214.109 on Android allow attackers to cause a denial of service or possibly have other impact via unknown vectors.

libksba: integer overflow in the BER decoder src/ber-decoder.c (ber_decoder_s)

ber-decoder.c in Libksba before 1.3.3 uses an incorrect integer data type, which allows remote attackers to cause a denial of service (crash) via crafted BER data, which leads to a buffer overflow.

chromium-browser: privilege escalation in service workers

The OriginCanAccessServiceWorkers function in content/browser/service_worker/service_worker_dispatcher_host.cc in Google Chrome before 40.0.2214.111 on Windows, OS X, and Linux and before 40.0.2214.109 on Android does not properly restrict the URI scheme during a ServiceWorker registration, which allows remote attackers to gain privileges via a filesystem: URI.

libksba: encoding of invalid utf-8 strings in DN decoder src/dn.c (append_quoted, append_atv)

The append_utf8_value function in the DN decoder (dn.c) in Libksba before 1.3.3 allows remote attackers to cause a denial of service (out-of-bounds read) by clearing the high bit of the byte after invalid utf-8 encoded data.

glibc: libtirpc: stack (frame) overflow in Sun RPC clntudp_call()

Stack-based buffer overflow in the clntudp_call function in sunrpc/clnt_udp.c in the GNU C Library (aka glibc or libc6) allows remote servers to cause a denial of service (crash) or possibly unspecified other impact via a flood of crafted ICMP and UDP packets.

Qemu: scsi: esp: OOB write while writing to 's->cmdbuf' in esp_reg_write

The esp_reg_write function in hw/scsi/esp.c in the 53C9X Fast SCSI Controller (FSC) support in QEMU does not properly check command buffer length, which allows local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) or potentially execute arbitrary code on the QEMU host via unspecified vectors.

chromium-browser: cross-origin-bypass in V8 bindings

The V8ThrowException::createDOMException function in bindings/core/v8/V8ThrowException.cpp in the V8 bindings in Blink, as used in Google Chrome before 40.0.2214.111 on Windows, OS X, and Linux and before 40.0.2214.109 on Android, does not properly consider frame access restrictions during the throwing of an exception, which allows remote attackers to bypass the Same Origin Policy via a crafted web site.

chromium-browser: use-after-free in DOM

Use-after-free vulnerability in the VisibleSelection::nonBoundaryShadowTreeRootNode function in core/editing/VisibleSelection.cpp in the DOM implementation in Blink, as used in Google Chrome before 40.0.2214.111 on Windows, OS X, and Linux and before 40.0.2214.109 on Android, allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted JavaScript code that triggers improper handling of a shadow-root anchor.

libxml2: Inappropriate fetch of entities content

XML external entity (XXE) vulnerability in the xmlStringLenDecodeEntities function in parser.c in libxml2 before 2.9.4, when not in validating mode, allows context-dependent attackers to read arbitrary files or cause a denial of service (resource consumption) via unspecified vectors.

nginx: NULL pointer dereference while writing client request body

os/unix/ngx_files.c in nginx before 1.10.1 and 1.11.x before 1.11.1 allows remote attackers to cause a denial of service (NULL pointer dereference and worker process crash) via a crafted request, involving writing a client request body to a temporary 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.

An issue was discovered in Apport before 2.20.4. In apport/ui.py, Apport reads the CrashDB field and it then evaluates the field as Python code if it begins with a "{". This allows remote attackers to execute arbitrary Python code.

chromium-browser: multiple unspecified vulnerabilities

Multiple unspecified vulnerabilities in Google Chrome before 40.0.2214.91 allow attackers to cause a denial of service or possibly have other impact via unknown vectors.

Off-by-one error in the extracthalf function in dpkg-deb/extract.c in the dpkg-deb component in Debian dpkg 1.16.x before 1.16.17 and 1.17.x before 1.17.26 allows remote attackers to execute arbitrary code via the archive magic version number in an "old-style" Debian binary package, which triggers a stack-based buffer overflow.

nbd-server.c in Network Block Device (nbd-server) before 3.11 does not properly handle signals, which allows remote attackers to cause a denial of service (deadlock) via unspecified vectors.

The dpkg-source command in Debian dpkg before 1.16.16 and 1.17.x before 1.17.25 allows remote attackers to bypass signature verification via a crafted Debian source control file (.dsc).

kernel: Race condition in packet_set_ring leads to use after free

Race condition in net/packet/af_packet.c in the Linux kernel through 4.8.12 allows local users to gain privileges or cause a denial of service (use-after-free) by leveraging the CAP_NET_RAW capability to change a socket version, related to the packet_set_ring and packet_setsockopt functions.

squid: Cache poisoning issue in HTTP Request handling

client_side.cc in Squid before 3.5.18 and 4.x before 4.0.10 does not properly ignore the Host header when absolute-URI is provided, which allows remote attackers to conduct cache-poisoning attacks via an HTTP request.

python-django: user with hardcoded password created when running tests on Oracle

Django 1.8.x before 1.8.16, 1.9.x before 1.9.11, and 1.10.x before 1.10.3 use a hardcoded password for a temporary database user created when running tests with an Oracle database, which makes it easier for remote attackers to obtain access to the database server by leveraging failure to manually specify a password in the database settings TEST dictionary.

Mozilla: TLS TURN and STUN connections silently fail to simple TCP connections (MFSA 2015-15)

The WebRTC subsystem in Mozilla Firefox before 36.0 recognizes turns: and stuns: URIs but accesses the TURN or STUN server without using TLS, which makes it easier for man-in-the-middle attackers to discover credentials by spoofing a server and completing a brute-force attack within a short time window.
