[0-Day] Issue 1335688 ($5,000) Google Chrome ANGLE CompressedTexImage3D Heap Buffer Overflow

by l33d0hyun 2022. 11. 11.
Google Chrome

Title

Summary

  • A Heap-Based Buffer Overflow vulnerability exists in the TextureGL::setCompressedImage function.
  • An attacker must open a arbitrary generated html file to exploit this vulnerability.

Test environment

  • macOS Monterey 12.4(21F79)
  • Google Chrome 103.0.5060.53

Root Cause Analysis

angle::Result TextureGL::setCompressedImage(const gl::Context *context,
                                            const gl::ImageIndex &index,

                                            size_t imageSize,
                                            const uint8_t *pixels)
{
    const FunctionsGL *functions      = GetFunctionsGL(context);
    StateManagerGL *stateManager      = GetStateManagerGL(context);
    const angle::FeaturesGL &features = GetFeaturesGL(context);

    gl::TextureTarget target = index.getTarget();
    size_t level             = static_cast<size_t>(index.getLevelIndex());
    ASSERT(TextureTargetToType(target) == getType());

    const gl::InternalFormat &originalInternalFormatInfo =
        gl::GetSizedInternalFormatInfo(internalFormat);
    nativegl::CompressedTexImageFormat compressedTexImageFormat =
        nativegl::GetCompressedTexImageFormat(functions, features, internalFormat);

    stateManager->bindTexture(getType(), mTextureID);
    if (nativegl::UseTexImage2D(getType()))
    {
        ASSERT(size.depth == 1);
        ANGLE_GL_TRY_ALWAYS_CHECK(
            context, functions->compressedTexImage2D(ToGLenum(target), static_cast<GLint>(level),
                                                     compressedTexImageFormat.internalFormat,
                                                     size.width, size.height, 0,
                                                     static_cast<GLsizei>(imageSize), pixels));     // [1]
    }
    else
    {
    ''' cut
}
  • The vulnerability occurs in comment [1]. The cause of this vulnerability is that when WebGL calls the compressedTexImage2D function, a Heap Buffer Overflow occurs during pixel processing.
