There are 6 open security issues in buster.
1 important issue:
When using a sync_repl client in 389-ds-base, an authenticated attacker can cause a NULL pointer dereference using a specially crafted query, causing a crash.
4 issues left for the package maintainer to handle:
A flaw has been found in 389-ds-base versions 1.4.x.x before 18.104.22.168. When executed in verbose mode, the dscreate and dsconf commands may display sensitive information, such as the Directory Manager password. An attacker, able to see the screen or record the terminal standard error output, could use this flaw to gain sensitive information.
A flaw was found in the 'deref' plugin of 389-ds-base where it could use the 'search' permission to display attribute values. In some configurations, this could allow an authenticated attacker to view private attributes, such as password hashes.
In 389-ds-base up to version 22.214.171.124, requests are handled by workers threads. Each sockets will be waited by the worker for at most 'ioblocktimeout' seconds. However this timeout applies only for un-encrypted requests. Connections using SSL/TLS are not taking this timeout into account during reads, and may hang longer.An unauthenticated attacker could repeatedly create hanging LDAP requests to hang all the workers, resulting in a Denial of Service.
You can find information about how to handle these issues in the security team's documentation.
