      <title>CVE-2022-23001 — Sweet-B Library: Point compress/decompress using the wrong bit for sign</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2022-23001</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Western Digital Sweet B Library&lt;/p&gt;
&lt;p&gt;When compressing or decompressing elliptic curve points using the Sweet B library, an incorrect choice of sign bit is used. An attacker with user level privileges and no other user&amp;#39;s assistance can exploit this vulnerability with only knowledge of the public key and the library. The resulting output may cause an error when used in other operations; for instance, verification of a valid signature under a decompressed public key may fail. This may be leveraged by an attacker to cause an error scenario in applications which use the library, resulting in a limited denial of service for an individual user. The scope of impact cannot extend to other components.&lt;/p&gt;</description>
