  • Prepare and upload:

    • dyssol_1.1.1+ds1-1
  • [DLA-3399-1] 389-ds-base_1.4.0.21-1+deb10u1

    • CVE-2021-4091: A double free was found in the way 389-ds-base handles virtual attributes context in persistent searches. An attacker could send a series of search requests, forcing the server to behave unexpectedly, and crash.

    • CVE-2022-0918: an unauthenticated attacker with network access to the LDAP port can cause a denial of service. The denial of service is triggered by a single message sent over a TCP connection, no bind or other authentication is required. The message triggers a segmentation fault that results in slapd crashing.

    • CVE-2022-0996: expired password was still allowed to access the database. A user whose password was expired was still allowed to access the database as if the password was not expired. Once a password is expired, and “grace logins” have been used up, the account is basically supposed to be locked out and should not be allowed to perform any privileged action.

    • CVE-2022-2850: the vulnerability in content synchronization plugin enables an authenticated attacker to trigger a denial of service via a crafted query through a NULL pointer dereference.

    • CVE-2021-3652: importing an asterisk as password hashes enables successful authentication with any password, allowing attackers to access accounts with disabled passwords.

    • CVE-2021-3514: if a sync_repl client is used, an authenticated attacker can trigger a crash by exploiting a specially crafted query that leads to a NULL pointer dereference.

    • CVE-2019-14824: the ‘deref’ plugin of 389-ds-base has a vulnerability that enables it to disclose attribute values using the ‘search’ permission. In certain setups, an authenticated attacker can exploit this flaw to access confidential attributes, including password hashes.

    • CVE-2019-10224: the vulnerability may disclose sensitive information, such as the Directory Manager password, when the dscreate and dsconf commands are executed in verbose mode. An attacker who can view the screen or capture the terminal standard error output can exploit this vulnerability to obtain confidential information.

    • CVE-2019-3883: SSL/TLS requests do not enforce ioblocktimeout limit, leading to DoS vulnerability by hanging all workers with hanging LDAP requests.
