Debian DLA-2611-1 : ldb security update

high Nessus Plugin ID 148272

Synopsis

The remote Debian host is missing a security update.

Description

Two issues have been found in ldb, an LDAP-like embedded database, for example used with samba.

Both issues are related to out of bounds access, either an out of bound read or a heap corrupton, both most likely leading to an application crash.

For Debian 9 stretch, these problems have been fixed in version 2:1.1.27-1+deb9u2.

We recommend that you upgrade your ldb packages.

For the detailed security status of ldb please refer to its security tracker page at: https://security-tracker.debian.org/tracker/ldb

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
