DESCRIPTION

A buffer overflow issue was addressed with improved memory handling. This issue is fixed in tvOS 15.2, macOS Monterey 12.1, Safari 15.2, iOS 15.2 and iPadOS 15.2, watchOS 8.3. Processing maliciously crafted web content may lead to arbitrary code execution. apple's Safari Classic buffer overflow vulnerabilities exist in products from multiple vendors.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. (CVE-2020-27918) "Clear History and Website Data" did not clear the history. A user may be unable to fully delete browsing history. This issue is fixed in macOS Big Sur 11.2, Security Update 2021-001 Catalina, Security Update 2021-001 Mojave. (CVE-2021-1789) A port redirection issue was found in WebKitGTK and WPE WebKit in versions prior to 2.30.6. A malicious website may be able to access restricted ports on arbitrary servers. The highest threat from this vulnerability is to data integrity. 14610.4.3.1.7 and 15610.4.3.1.7), watchOS 7.3.2, macOS Big Sur 11.2.3. Apple is aware of a report that this issue may have been actively exploited.. (CVE-2021-1870) A use-after-free vulnerability exists in the way certain events are processed for ImageLoader objects of Webkit WebKitGTK 2.30.4. In order to trigger the vulnerability, a victim must be tricked into visiting a malicious webpage. (CVE-2021-21775) A use-after-free vulnerability exists in the way Webkit's GraphicsContext handles certain events in WebKitGTK 2.30.4. A victim must be tricked into visiting a malicious web page to trigger this vulnerability. (CVE-2021-21779) An exploitable use-after-free vulnerability exists in WebKitGTK browser version 2.30.3 x64. The victim needs to visit a malicious web site to trigger the vulnerability. Apple is aware of a report that this issue may have been actively exploited.. Apple is aware of a report that this issue may have been actively exploited.. Apple is aware of a report that this issue may have been actively exploited.. A malicious application may be able to leak sensitive user information. A malicious website may be able to access restricted ports on arbitrary servers. Apple is aware of a report that this issue may have been actively exploited.. Apple is aware of a report that this issue may have been actively exploited.. (CVE-2021-30799) A use-after-free flaw was found in WebKitGTK. (CVE-2021-30809) A confusion type flaw was found in WebKitGTK. (CVE-2021-30818) An out-of-bounds read flaw was found in WebKitGTK. A specially crafted audio file could use this flaw to trigger a disclosure of memory when processed. (CVE-2021-30887) An information leak flaw was found in WebKitGTK. A malicious web site using Content Security Policy reports could use this flaw to leak information via redirects. (CVE-2021-30888) A buffer overflow flaw was found in WebKitGTK.

Reason: This candidate was in a CNA pool that was not assigned to any issues during 2021. Notes: none. (CVE-2021-32912) BubblewrapLauncher.cpp in WebKitGTK and WPE WebKit prior to 2.34.1 allows a limited sandbox bypass that allows a sandboxed process to trick host processes into thinking the sandboxed process is not confined by the sandbox, by abusing VFS syscalls that manipulate its filesystem namespace. The impact is limited to host services that create UNIX sockets that WebKit mounts inside its sandbox, and the sandboxed process remains otherwise confined. NOTE: this is similar to CVE-2021-41133. (CVE-2021-42762) A segmentation violation vulnerability was found in webkitgtk. An attacker with network access could pass specially crafted HTML files causing an application to halt or crash. (CVE-2021-45481) A use-after-free vulnerability was found in webkitgtk. An attacker with network access could pass specially crafted HTML files causing an application to halt or crash. (CVE-2021-45482) A use-after-free vulnerability was found in webkitgtk. An attacker with network access could pass specially crafted HTML files causing an application to halt or crash. Video self-preview in a webRTC call may be interrupted if the user answers a phone call. An app may be able to disclose kernel memory. Visiting a website that frames malicious content may lead to UI spoofing. Visiting a malicious website may lead to user interface spoofing. Apple is aware of a report that this issue may have been actively exploited against versions of iOS released before iOS 15.1.. (CVE-2022-46700) A flaw was found in the WebKitGTK package. An improper input validation issue may lead to a use-after-free vulnerability. This may, in theory, allow a remote malicious user to create a specially crafted web page, trick the victim into opening it, trigger type confusion, and execute arbitrary code on the target system. (CVE-2023-23529) A use-after-free vulnerability in WebCore::RenderLayer::addChild in WebKitGTK prior to 2.36.8 allows malicious users to execute code remotely.
