      <title>GHSA-qg8r-f7x3-25f7 — imageproc: Out-of-bounds read via NaN coordinates in bilinear/bicubic sampling</title>
      <link>https://cve.radiocsirt.org/vuln/ghsa-qg8r-f7x3-25f7</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; crates.io: imageproc&lt;/p&gt;
&lt;p&gt;A bounds check was performed in floating points before a cast to the index passed to an unchecked access function. This checked considered `NaN` cases improperly, causing them to succeed the check instead of failing it. The floating point coordinate is under caller control by passing a selected projection matrix.&lt;/p&gt;
&lt;p&gt;Carefully controlling the coordinates of an image with no data and one non-zero dimension provides an arbitrary read primitive in the first 32-bits of address space with a Bilinear sampling method.&lt;/p&gt;
&lt;p&gt;Using bicubic sampling can result in a read of a few bytes beyond an allocation.&lt;/p&gt;
&lt;p&gt;Other out-of-bounds reads may be possible.&lt;/p&gt;</description>
