Debian LTS Advisory ([SECURITY] [DLA 1779-1] 389-ds-base security update)

Published: 2019-05-07 02:00:12
CVE Author: NIST National Vulnerability Database (NVD)

CVSS Base Vector:

The remote host is missing an update for the '389-ds-base' Linux Distribution Package(s) announced via the DSA-1779-1 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
In 389-ds-base up to version, requests were handled by worker threads. Each socket had been waited for by the worker for at most 'ioblocktimeout' seconds. However, this timeout applied only to un-encrypted requests. Connections using SSL/TLS were not taking this timeout into account during reads, and may have hung longer. An unauthenticated attacker could have repeatedly created hanging LDAP requests to hang all the workers, resulting in a Denial of Service.

Affected Versions:
'389-ds-base' Linux Distribution Package(s) on Debian Linux.

For Debian 8 'Jessie', this problem has been fixed in version We recommend that you upgrade your 389-ds-base Linux Distribution Packages.

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package
