Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
– JFS file system;
– BPF subsystem;
– Netfilter;
(CVE-2023-52600, CVE-2024-26589, CVE-2024-26591, CVE-2024-26581,
CVE-2023-52603)
What is the Attack?
Cisco issued an advisory on 24th April, regarding its Adaptive Security Appliances, multifunctional devices combining firewall, VPN, and other security functions. It reported that these appliances had become the focus of state-sponsored espionage, with attackers exploiting two previously unknown vulnerabilities to infiltrate government entities worldwide. In this campaign, two backdoors were deployed: “Line Runner” and “Line Dancer.” These backdoors operated in tandem to execute various malicious activities on the target systems, encompassing configuration alterations, reconnaissance, capturing/exfiltrating network traffic, and potentially facilitating lateral movement.
What is the recommended Mitigation?
According to Cisco’s advisory, the initial attack vector remains unidentified, two vulnerabilities (CVE-2024-20353 and CVE-2024-20359) have been pinpointed. Customers are strongly urged to adhere to the instructions outlined in the security advisories provided. https://sec.cloudapps.cisco.com/security/center/resources/asa_ftd_attacks_event_response
What FortiGuard Coverage is available?
FortiGuard Labs has blocked all the known Indicators of compromise (IoCs) related to this campaign as listed on Cisco’s advisory and is currently investigating for further protections. Meanwhile, FortiGuard Labs recommends users apply patches as provided by Cisco’s Product Security Incident Response Team (PSIRT).
USN-6657-1 fixed several vulnerabilities in Dnsmasq. This update provides
the corresponding update for Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.
Original advisory details:
Elias Heftrig, Haya Schulmann, Niklas Vogel, and Michael Waidner discovered
that Dnsmasq icorrectly handled validating DNSSEC messages. A remote
attacker could possibly use this issue to cause Dnsmasq to consume
resources, leading to a denial of service. (CVE-2023-50387)
It was discovered that Dnsmasq incorrectly handled preparing an NSEC3
closest encloser proof. A remote attacker could possibly use this issue to
cause Dnsmasq to consume resources, leading to a denial of service.
(CVE-2023-50868)
It was discovered that Dnsmasq incorrectly set the maximum EDNS.0 UDP
packet size as required by DNS Flag Day 2020. This issue only affected
Ubuntu 23.10. (CVE-2023-28450)
Multiple vulnerabilities have been discovered in Google Chrome, which could allow for arbitrary code execution. Successful exploitation of these vulnerabilities could allow for arbitrary code execution in the context of the logged on user. Depending on the privileges associated with the user an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
