      <title>CVE-2023-39323 — Arbitrary code execution during build via line directives in cmd/go</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2023-39323</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Go toolchain cmd/go&lt;/p&gt;
&lt;p&gt;Line directives (&amp;#34;//line&amp;#34;) can be used to bypass the restrictions on &amp;#34;//go:cgo_&amp;#34; directives, allowing blocked linker and compiler flags to be passed during compilation. This can result in unexpected execution of arbitrary code when running &amp;#34;go build&amp;#34;. The line directive requires the absolute path of the file in which the directive lives, which makes exploiting this issue significantly more complex.&lt;/p&gt;</description>
