Debian DLA-2652-1 : unbound1.9 security update

critical Nessus Plugin ID 149342

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Several security vulnerabilities have been discovered in Unbound, a validating, recursive, caching DNS resolver, by security researchers of X41 D-SEC located in Aachen, Germany. Integer overflows, assertion failures, an out-of-bound write and an infinite loop vulnerability may lead to a denial of service or have a negative impact on data confidentiality.

For Debian 9 stretch, these problems have been fixed in version 1.9.0-2+deb10u2~deb9u2.

We recommend that you upgrade your unbound1.9 packages.

For the detailed security status of unbound1.9 please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/unbound1.9

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.
