Summary
======
The package chromium before version 52.0.2743.116-1 is vulnerable to
multiple issues.

Resolution
=========
Upgrade to 52.0.2743.116-1.

# pacman -Syu "chromium>=52.0.2743.116-1"

The problems have been fixed upstream in version 52.0.2743.116.

Workaround
=========
None.

Description
==========
- CVE-2016-5139 (arbitrary code execution)

Multiple integer overflows in the opj_tcd_init_tile function in tcd.c in
OpenJPEG, as used in PDFium, allow remote attackers to cause a denial of
service (heap-based buffer overflow) or possibly have other unspecified
impact via crafted JPEG 2000 data.

- CVE-2016-5140 (arbitrary code execution)

Heap-based buffer overflow in the opj_j2k_read_SQcd_SQcc function in
j2k.c in OpenJPEG, as used in PDFium, allows remote attackers to cause a
denial of service or possibly have other unspecified impact via crafted
JPEG 2000 data.

- CVE-2016-5141 (address bar spoofing)

Blink allows remote attackers to spoof the address bar via vectors
involving a provisional URL for an initially empty document, related to
FrameLoader.cpp and ScopedPageLoadDeferrer.cpp.

- CVE-2016-5142 (arbitrary code execution)

The Web Cryptography API (aka WebCrypto) implementation in Blink does
not properly copy data buffers, which allows remote attackers to cause a
denial of service (use-after-free) or possibly have other unspecified
impact via crafted JavaScript code, related to NormalizeAlgorithm.cpp
and SubtleCrypto.cpp.

- CVE-2016-5143, CVE-2016-5144 (access restriction bypass)

The Developer Tools (aka DevTools) subsystem in Blink mishandles the
script-path hostname, remoteBase parameter, and remoteFrontendUrl
parameter, which allows remote attackers to bypass intended access
restrictions via a crafted URL.

- CVE-2016-5145 (same-origin policy bypass)

Blink does not ensure that a taint property is preserved after a
structure-clone operation on an ImageBitmap object derived from a
cross-origin image, which allows remote attackers to bypass the Same
Origin Policy via crafted JavaScript code.

- CVE-2016-5146 (arbitrary code execution)

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

Impact
=====
A remote attacker can execute arbitrary code on the affected host.
