Security updates available for Adobe Connect | APSB18-22
|Bulletin ID              |Date Published                  |Priority          |
|APSB18-22                |July 10, 2018                   |2                 |


Adobe has released a security update for Adobe Connect.  This update resolves an
important authentication bypass vulnerability (CVE-2018-4994), which could
result in sensitive information disclosure if successfully exploited.  This
update also resolves an important session management vulnerability due to
inadequate validation of Connect meeting session tokens.  Finally, the Connect
add-in installer prior to 9.7 insecurely loads DLL files, which could be abused
to escalate local privileges.
