This requires ability to +directly modify dovecot indexes. +Steps to reproduce: +Produce dovecot.index.log entry that creates an FTS header which has +more than 12 bytes of data. +Trigger dovecot indexer-worker or run doveadm index. +Dovecot will crash. + +Mitigations: +Since 2.3.0 dovecot has been compiled with stack smash protection, ASLR, +read-only GOT tables and other techniques that make exploiting this bug +much harder.</p> + </blockquote> + </body> + </description> + <references> + <url>http://cve.mitre.org/cgi-bin/cvename.cgi?name=2019-7524</url>; + <url>https://dovecot.org/list/dovecot-news/2019-March/000401.html</url>; + <cvename>CVE-2019-7524</cvename> + </references> + <dates> + <discovery>2019-02-05</discovery> + <entry>2019-03-28</entry> + </dates> + </vuln> + <vuln vid="94d63fd7-508b-11e9-9ba0-4c72b94353b5"> <topic>drupal -- Drupal core - Moderately critical - Cross Site Scripting</topic> <affects>
