Arch Linux Security Advisory ASA-201608-16 ========================================== Severity: Critical Date : 2016-08-17 CVE-ID : CVE-2016-5139 CVE-2016-5140 CVE-2016-5141 CVE-2016-5142 CVE-2016-5143 CVE-2016-5144 CVE-2016-5145 CVE-2016-5146 Package : chromium Type : multiple issues Remote : Yes Link : https://wiki.archlinux.org/index.php/CVE 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.
