- ------------------------------------------------------------------------- Debian LTS Advisory DLA-4021-1 [email protected] https://www.debian.org/lts/security/ Andrej Shadura January 19, 2025 https://wiki.debian.org/LTS
- -------------------------------------------------------------------------
Package : 389-ds-base Version : 1.4.4.11-2+deb11u1 CVE ID : CVE-2021-3652 CVE-2021-4091 CVE-2022-0918 CVE-2022-0996 CVE-2022-2850 CVE-2024-2199 CVE-2024-3657 CVE-2024-5953 CVE-2024-8445
This update fixes multiple vulnerabilities in 389-ds-base LDAP server.
CVE-2021-3652
If an asterisk is imported as password hashes, either accidentally or maliciously, then instead of being inactive, any password will successfully match during authentication. This flaw allows an attacker to successfully authenticate as a user whose password was disabled.
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
A vulnerability allows an unauthenticated attacker with network access to the LDAP port to 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
A vulnerability allows expired passwords to access the database to cause improper authentication.
CVE-2022-2850
When the content synchronization plugin is enabled, an authenticated user can reach a NULL pointer dereference using a specially crafted query. This flaw allows an authenticated attacker to cause a denial of service. This CVE is assigned against an incomplete fix of CVE-2021-3514.
CVE-2024-2199
A denial of service vulnerability that may allow an authenticated user to cause a server crash while modifying `userPassword` using malformed input.
CVE-2024-3657
A specially-crafted LDAP query can potentially cause a failure on the directory server, leading to a denial of service.
CVE-2024-5953
This issue may allow an authenticated user to cause a server denial of service while attempting to log in with a user with a malformed hash in their password.
CVE-2024-8445
The fix for CVE-2024-2199 in 389-ds-base was insufficient to cover all scenarios. In certain product versions, an authenticated user may cause a server crash while modifying `userPassword` using malformed input.
For Debian 11 bullseye, these problems have been fixed in version 1.4.4.11-2+deb11u1.
We recommend that you upgrade your 389-ds-base packages.
