TITLE

Multiple Apple product WebKit Component Buffer Error Vulnerability

DESCRIPTION

Multiple memory corruption issues were addressed with improved memory handling. This issue is fixed in iOS 12.4, macOS Mojave 10.14.6, tvOS 12.4, watchOS 5.3, Safari 12.1.2, iTunes for Windows 12.9.6, iCloud for Windows 7.13, iCloud for Windows 10.6. Processing maliciously crafted web content may lead to arbitrary code execution. WebKit is prone to a cross-site scripting vulnerability and multiple memory-corruption vulnerabilities. An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site or execute arbitrary code in the context of the affected system. This may allow the attacker to steal cookie-based authentication credentials and launch other attacks. Failed exploit attempts will likely cause a denial-of-service condition. Apple Safari, etc. are all products of Apple (Apple). Apple Safari is a web browser that is the default browser included with the Mac OS X and iOS operating systems. Apple iOS is an operating system developed for mobile devices. Apple tvOS is a smart TV operating system. WebKit is one of the web browser engine components. The following products and versions are affected: Apple iOS prior to 12.4; Windows-based iTunes prior to 12.9.6; tvOS prior to 12.4; Safari prior to 12.1.2; macOS Mojave prior to 10.14.6; watchOS prior to 5.3. WebKitGTK and WPE WebKit prior to version 2.24.1 failed to properly apply configured HTTP proxy settings when downloading livestream video (HLS, DASH, or Smooth Streaming), an error resulting in deanonymization. This issue was corrected by changing the way livestreams are downloaded. (CVE-2019-6237) WebKitGTK and WPE WebKit prior to version 2.24.1 are vulnerable to address bar spoofing upon certain JavaScript redirections. An attacker could cause malicious web content to be displayed as if for a trusted URI. This is similar to the CVE-2018-8383 issue in Microsoft Edge. (CVE-2019-8601) An out-of-bounds read was addressed with improved input validation. (CVE-2019-8644) A logic issue existed in the handling of synchronous page loads. (CVE-2019-8689) A logic issue existed in the handling of document loads. (CVE-2019-8719) This fixes a remote code execution in webkitgtk4. No further details are available in NIST. This issue is fixed in watchOS 6.1. This issue is fixed in watchOS 6.1. This issue is fixed in watchOS 6.1. (CVE-2019-8766) "Clear History and Website Data" did not clear the history. The issue was addressed with improved data deletion. This issue is fixed in macOS Catalina 10.15. A user may be unable to delete browsing history items. (CVE-2019-8768) An issue existed in the drawing of web page elements. Visiting a maliciously crafted website may reveal browsing history. (CVE-2019-8769) This issue was addressed with improved iframe sandbox enforcement. (CVE-2019-8846) WebKitGTK up to and including 2.26.4 and WPE WebKit up to and including 2.26.4 (which are the versions right prior to 2.28.0) contains a memory corruption issue (use-after-free) that may lead to arbitrary code execution. (CVE-2020-10018) A use-after-free flaw exists in WebKitGTK. A malicious website may be able to cause a denial of service. A DOM object context may not have had a unique security origin. A file URL may be incorrectly processed. (CVE-2020-3885) A race condition was addressed with additional validation. An application may be able to read restricted memory. (CVE-2020-3901) An input validation issue was addressed with improved input validation. (CVE-2020-3902). CVE-2019-8649: Sergei Glazunov of Google Project Zero Installation note: Safari 12.1.2 may be obtained from the Mac App Store. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-4515-1 security@debian.org https://www.debian.org/security/ Alberto Garcia September 04, 2019 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : webkit2gtk CVE ID : CVE-2019-8644 CVE-2019-8649 CVE-2019-8658 CVE-2019-8666 CVE-2019-8669 CVE-2019-8671 CVE-2019-8672 CVE-2019-8673 CVE-2019-8676 CVE-2019-8677 CVE-2019-8678 CVE-2019-8679 CVE-2019-8680 CVE-2019-8681 CVE-2019-8683 CVE-2019-8684 CVE-2019-8686 CVE-2019-8687 CVE-2019-8688 CVE-2019-8689 CVE-2019-8690 Several vulnerabilities have been discovered in the webkit2gtk web engine: CVE-2019-8644 G.
