CVSS: 5.9EPSS: 0%CPEs: 3EXPL: 0CVE-2023-7008 – Systemd-resolved: unsigned name response in signed zone is not refused when dnssec=yes
https://notcve.org/view.php?id=CVE-2023-7008
A vulnerability was found in systemd-resolved. This issue may allow systemd-resolved to accept records of DNSSEC-signed domains even when they have no signature, allowing man-in-the-middles (or the upstream DNS resolver) to manipulate records. Se encontró una vulnerabilidad en systemd-resolved. Este problema puede permitir que systemd-resolved acepte registros de dominios firmados por DNSSEC incluso cuando no tienen firma, lo que permite que los intermediarios (o el solucionador de DNS ascendente) manipulen los registros. • https://access.redhat.com/errata/RHSA-2024:2463 https://access.redhat.com/errata/RHSA-2024:3203 https://access.redhat.com/security/cve/CVE-2023-7008 https://bugzilla.redhat.com/show_bug.cgi?id=2222261 https://bugzilla.redhat.com/show_bug.cgi?id=2222672 https://github.com/systemd/systemd/issues/25676 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/4GMDEG5PKONWNHOEYSUDRT6JEOISRMN2 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject • CWE-300: Channel Accessible by Non-Endpoint •
CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 2CVE-2023-26604 – systemd: privilege escalation via the less pager
https://notcve.org/view.php?id=CVE-2023-26604
systemd before 247 does not adequately block local privilege escalation for some Sudo configurations, e.g., plausible sudoers files in which the "systemctl status" command may be executed. Specifically, systemd does not set LESSSECURE to 1, and thus other programs may be launched from the less program. This presents a substantial security risk when running systemctl from Sudo, because less executes as root when the terminal size is too small to show the complete systemctl output. A vulnerability was found in the systemd package. The systemd package does not adequately block local privilege escalation for some Sudo configurations, for example, plausible sudoers files, in which the "systemctl status" command may be executed. • https://github.com/Zenmovie/CVE-2023-26604 http://packetstormsecurity.com/files/174130/systemd-246-Local-Root-Privilege-Escalation.html https://blog.compass-security.com/2012/10/dangerous-sudoers-entries-part-2-insecure-functionality https://github.com/systemd/systemd/blob/main/NEWS#L4335-L4340 https://lists.debian.org/debian-lts-announce/2023/03/msg00032.html https://medium.com/%40zenmoviefornotification/saidov-maxim-cve-2023-26604-c1232a526ba7 https://security.netapp.com/advisory/ntap-20230505-0009 https:& •

CVSS: 9.8EPSS: 0%CPEs: 10EXPL: 0CVE-2022-2526 – systemd-resolved: use-after-free when dealing with DnsStream in resolved-dns-stream.c
https://notcve.org/view.php?id=CVE-2022-2526
A use-after-free vulnerability was found in systemd. This issue occurs due to the on_stream_io() function and dns_stream_complete() function in 'resolved-dns-stream.c' not incrementing the reference counting for the DnsStream object. Therefore, other functions and callbacks called can dereference the DNSStream object, causing the use-after-free when the reference is still used later. Se ha encontrado una vulnerabilidad de uso de memoria previamente liberada en systemd. Este problema ocurre debido a que las funciones on_stream_io() y dns_stream_complete() en "resolved-dns-stream.c" no incrementan el conteo de referencias para el objeto DnsStream. • https://github.com/systemd/systemd/commit/d973d94dec349fb676fdd844f6fe2ada3538f27c https://security.netapp.com/advisory/ntap-20221111-0005 https://access.redhat.com/security/cve/CVE-2022-2526 https://bugzilla.redhat.com/show_bug.cgi?id=2109926 • CWE-416: Use After Free •
