Arch Linux Security Advisory ASA-201601-28 ========================================== Severity: Critical Date : 2016-01-25 CVE-ID : CVE-2016-1612 CVE-2016-1613 CVE-2016-1614 CVE-2016-1615 CVE-2016-1616 CVE-2016-1617 CVE-2016-1618 CVE-2016-1619 CVE-2016-1620 Package : chromium Type : multiple issues Remote : Yes Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package chromium before version 48.0.2564.82-1 is vulnerable to multiple issues. Resolution ========== Upgrade to 48.0.2564.82-1. # pacman -Syu "chromium>=48.0.2564.82-1" The problem has been fixed upstream in version 48.0.2564.82. Workaround ========== None. Description =========== - CVE-2016-1612: The LoadIC::UpdateCaches function in ic/ic.cc in Google V8 does not ensure receiver compatibility before performing a cast of an unspecified variable, which allows remote attackers to cause a denial of service or possibly have unknown other impact via crafted JavaScript code. Credit to cloudfuzzer. - CVE-2016-1613: Multiple use-after-free vulnerabilities in the formfiller implementation in PDFium allow remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted PDF document, related to improper tracking of the destruction of (1) IPWL_FocusHandler and (2) IPWL_Provider objects. - CVE-2016-1614: The UnacceleratedImageBufferSurface class in WebKit/Source/platform/graphics/UnacceleratedImageBufferSurface.cpp in Blink mishandles the initialization mode, which allows remote attackers to obtain sensitive information from process memory via a crafted web site.

Credit to Luan Herrera. - CVE-2016-1617: The CSPSource::schemeMatches function in WebKit/Source/core/frame/csp/CSPSource.cpp in the Content Security Policy (CSP) implementation in Blink does not apply http policies to https URLs and does not apply ws policies to wss URLs, which makes it easier for remote attackers to determine whether a specific HSTS web site has been visited by reading a CSP report. Credit to Yan Zhu. - CVE-2016-1618: Blink does not ensure that a proper cryptographicallyRandomValues random number generator is used, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via unspecified vectors.

Credit to Keve Nagy. - CVE-2016-1620: Various fixes from internal audits, fuzzing and other initiatives. Impact ====== A remote attacker might be able to cause a denial of service, access sensitive information or execute arbitrary code on the affected host.
