Debian DSA-5316-1 : netty - security update

medium Nessus Plugin ID 169929

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 11 host has a package installed that is affected by multiple vulnerabilities as referenced in the dsa-5316 advisory.

 Several out-of-memory, stack overflow or HTTP request smuggling vulnerabilities have been discovered in Netty, a Java NIO client/server socket framework, which may allow attackers to cause a denial of service or bypass restrictions when used as a proxy. For the stable distribution (bullseye), these problems have been fixed in version 1:4.1.48-4+deb11u1. We recommend that you upgrade your netty packages. For the detailed security status of netty please refer to its security tracker page at: https://security- tracker.debian.org/tracker/netty

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the netty packages.

For the stable distribution (bullseye), these problems have been fixed in version 1
