Description John Helmert III archtester

CVE-2022-30293 (https://bugs.webkit.org/show_bug.cgi?id=237187):

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.

CVE-2022-30294 (https://bugs.webkit.org/show_bug.cgi?id=237188):

In WebKitGTK through 2.36.0 (and WPE WebKit), there is a use-after-free in WebCore::TextureMapperLayer::setContentsLayer in WebCore/platform/graphics/texmap/TextureMapperLayer.cpp.

These are duplicates. There is a patch:

https://github.com/WebKit/WebKit/commit/fb8ed3d7e9868de82621015783d1f0cc1080b4e4

But I don't know how to parse those tags, so unsure if this has made it into a release.

Comment 1 John Helmert III archtester

2.36.3 has been released with fixes "several crashes and rendering issues" (read: multiple code execution issues).

These are apparently in 2.36.1.
