A use-after-free vulnerability in WebCore::RenderLayer::repaintBlockSelectionGaps in WebKitGTK before 2.36.8 allows attackers to execute code remotely.
A use-after-free vulnerability in WebCore::RenderLayer::updateDescendantDependentFlags in WebKitGTK before 2.36.8 allows attackers to execute code remotely.
An out-of-bounds write issue was addressed with improved bounds checking. This issue is fixed in iOS 15.6.1 and iPadOS 15.6.1, macOS Monterey 12.5.1, Safari 15.6.1. Processing maliciously crafted web content may lead to arbitrary code execution. Apple is aware of a report that this issue may have been actively exploited.
Heap buffer overflow in WebRTC in Google Chrome prior to 103.0.5060.114 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.
In WebKitGTK through 2.36.0 (and WPE WebKit), there is a heap-based buffer overflow in WebCore::TextureMapperLayer::setContentsLayer in WebCore/platform/graphics/texmap/TextureMapperLayer.cpp.
A use after free issue was addressed with improved memory management. This issue is fixed in iOS 15.3 and iPadOS 15.3, watchOS 8.4, tvOS 15.3, Safari 15.3, macOS Monterey 12.2. Processing maliciously crafted web content may lead to arbitrary code execution.
In WebKitGTK before 2.32.4, there is incorrect memory allocation in WebCore::ImageBufferCairoImageSurfaceBackend::create, leading to a segmentation violation and application crash, a different vulnerability than CVE-2021-30889.
