Vulnerability from variot

An issue was discovered in certain Apple products. iOS before 11.4 is affected. Safari before 11.1.1 is affected. iCloud before 7.5 on Windows is affected. iTunes before 12.7.5 on Windows is affected. tvOS before 11.4 is affected. The issue involves the "WebKit" component. It allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) via a crafted web site. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the handling of SVG elements. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code under the context of the current process. Apple iOS is an operating system developed for mobile devices; Safari is a web browser that is the default browser included with Mac OS X and iOS operating systems. WebKit is one of the web browser engine components. The following products and versions are affected: Apple iOS prior to 11.4; Safari prior to 11.1.1; Windows-based iCloud prior to 7.5; Windows-based iTunes prior to 12.7.5; tvOS prior to 11.4. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201808-04

    "data": "An issue was discovered in certain Apple products. iOS before 11.4 is affected. Safari before 11.1.1 is affected. iCloud before 7.5 on Windows is affected. iTunes before 12.7.5 on Windows is affected. tvOS before 11.4 is affected. The issue involves the \"WebKit\" component. It allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) via a crafted web site. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the handling of SVG elements. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code under the context of the current process. Apple iOS is an operating system developed for mobile devices; Safari is a web browser that is the default browser included with Mac OS X and iOS operating systems. WebKit is one of the web browser engine components. The following products and versions are affected: Apple iOS prior to 11.4; Safari prior to 11.1.1; Windows-based iCloud prior to 7.5; Windows-based iTunes prior to 12.7.5; tvOS prior to 11.4. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\nGentoo Linux Security Advisory                           GLSA 201808-04\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n                                           https://security.gentoo.org/\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n\n Severity: Normal\n    Title: WebkitGTK+: Multiple vulnerabilities\n     Date: August 22, 2018\n     Bugs: #652820, #658168, #662974\n       ID: 201808-04\n\n- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -\n\nSynopsis\n========\n\nMultiple vulnerabilities have been found in WebKitGTK+, the worst of\nwhich may lead to arbitrary code execution. \n\nBackground\n==========\n\nWebKitGTK+ is a full-featured port of the WebKit rendering engine,\nsuitable for projects requiring any kind of web integration, from\nhybrid HTML/CSS applications to full-fledged web browsers. \n\nAffected packages\n=================\n\n    -------------------------------------------------------------------\n     Package              /     Vulnerable     /            Unaffected\n    -------------------------------------------------------------------\n  1  net-libs/webkit-gtk          \u003c 2.20.4                  \u003e= 2.20.4\n\nDescription\n===========\n\nMultiple vulnerabilities have been discovered in WebKitGTK+.

Please check our websites for information about the\nlatest stable releases. \n\nFurther information about WebKitGTK+ and WPE WebKit security advisories\ncan be found at https://webkitgtk.org/security.html or\nhttps://wpewebkit.org/security/. \n\nThe WebKitGTK+ and WPE WebKit team,\nJune 13, 2018\n. ==========================================================================\nUbuntu Security Notice USN-3687-1\nJune 18, 2018\n\nwebkit2gtk vulnerabilities\n==========================================================================\n\nA security issue affects these releases of Ubuntu and its derivatives:\n\n- Ubuntu 18.04 LTS\n- Ubuntu 17.10\n- Ubuntu 16.04 LTS\n\nSummary:\n\nSeveral security issues were fixed in WebKitGTK+. \n\nSoftware Description:\n- webkit2gtk: Web content engine library for GTK+\n\nDetails:\n\nA large number of security issues were discovered in the WebKitGTK+ Web and\nJavaScript engines. \n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 18.04 LTS:\n  libjavascriptcoregtk-4.0-18     2.20.3-0ubuntu0.18.04.1\n  libwebkit2gtk-4.0-37            2.20.3-0ubuntu0.18.04.1\n\nUbuntu 17.10:\n  libjavascriptcoregtk-4.0-18     2.20.3-0ubuntu0.17.10.1\n  libwebkit2gtk-4.0-37            2.20.3-0ubuntu0.17.10.1\n\nUbuntu 16.04 LTS:\n  libjavascriptcoregtk-4.0-18     2.20.3-0ubuntu0.16.04.1\n  libwebkit2gtk-4.0-37            2.20.3-0ubuntu0.16.04.1\n\nThis update uses a new upstream release, which includes additional bug\nfixes.
