A poorly chosen string hashing algorithm meant that the user could control which bucket their data was stored in, allowing a malicious user to direct many inputs to a single bucket. Each subsequent insertion to the same bucket requires a strcmp of every other entry in it. At tens of thousands of entries, each new insertion could keep the CPU busy in a strcmp loop for minutes. +The string hashing algorithm has been replaced with a better one, and now also uses a random seed per hash table, so malicious inputs cannot be precomputed.</p> + </blockquote> + </body> + </description> + <references> + <cvename>CVE-2021-33582</cvename> + <url>https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-33582</url> + </references> + <dates> + <discovery>2021-05-26</discovery> + <entry>2021-09-01</entry> + </dates> + </vuln> + <vuln vid="6c22bb39-0a9a-11ec-a265-001b217b3468"> <topic>Gitlab -- Vulnerabilities</topic> <affects> |
