Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:1520-1 advisory.

- The permission package in SUSE Linux Enterprise Server allowed all local users to run dumpcap in the easy permission profile and sniff network traffic. This issue affects: SUSE Linux Enterprise Server permissions versions starting from 85c83fef7e017f8ab7f8602d3163786d57344439 to 081d081dcfaf61710bda34bc21c80c66276119aa. (CVE-2019-3687)

- The /usr/sbin/pinger binary packaged with squid in SUSE Linux Enterprise Server 15 before and including version 4.8-5.8.1 and in SUSE Linux Enterprise Server 12 before and including 3.5.21-26.17.1 had squid:root, 0750 permissions. This allowed an attacker that compromissed the squid user to gain persistence by changing the binary (CVE-2019-3688)

- A UNIX Symbolic Link (Symlink) Following vulnerability in chkstat of SUSE Linux Enterprise Server 12, SUSE Linux Enterprise Server 15, SUSE Linux Enterprise Server 11 set permissions intended for specific binaries on other binaries because it erroneously followed symlinks. The symlinks can't be controlled by attackers on default systems, so exploitation is difficult. This issue affects: SUSE Linux Enterprise Server 12 permissions versions prior to 2015.09.28.1626-17.27.1. SUSE Linux Enterprise Server 15 permissions versions prior to 20181116-9.23.1. SUSE Linux Enterprise Server 11 permissions versions prior to 2013.1.7-0.6.12.1. (CVE-2020-8013)

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

Solution

Update the affected permissions and / or permissions-zypp-plugin packages.
