CVSS: 8.6EPSS: 1%CPEs: 12EXPL: 0CVE-2020-24606 – squid: Improper input validation could result in a DoS
https://notcve.org/view.php?id=CVE-2020-24606
Squid before 4.13 and 5.x before 5.0.4 allows a trusted peer to perform Denial of Service by consuming all available CPU cycles during handling of a crafted Cache Digest response message. This only occurs when cache_peer is used with the cache digests feature. The problem exists because peerDigestHandleReply() livelocking in peer_digest.cc mishandles EOF. Squid versiones anteriores a 4.13 y versiones 5.x anteriores a 5.0.4, permite que un peer de confianza lleve a cabo una Denegación de Servicio mediante el consumo de todos los ciclos de la CPU disponibles durante el manejo de un mensaje de respuesta de Cache Digest diseñado. Esto solo ocurre cuando cache_peer es usado con la funcionalidad cache digest. • http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00012.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00017.html http://www.squid-cache.org/Versions/v4/changesets/SQUID-2020_9.patch https://github.com/squid-cache/squid/security/advisories/GHSA-vvj7-xjgq-g2jg https://lists.debian.org/debian-lts-announce/2020/10/msg00005.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BE6FKUN7IGTIR2MEEMWYDT7N5EJJLZI2 https://lists.fedoraproje • CWE-20: Improper Input Validation CWE-667: Improper Locking •

https://notcve.org/view.php?id=CVE-2020-14367
A flaw was found in chrony versions before 3.5.1 when creating the PID file under the /var/run/chrony folder. The file is created during chronyd startup while still running as the root user, and when it's opened for writing, chronyd does not check for an existing symbolic link with the same file name. This flaw allows an attacker with privileged access to create a symlink with the default PID file name pointing to any destination file in the system, resulting in data loss and a denial of service due to the path traversal. Se detectó un fallo en chrony versiones anteriores a 3.5.1, al crear el archivo PID en la carpeta /var/run/chrony. El archivo es creado durante el inicio de chronyd mientras aún se ejecuta como usuario root, y cuando se abre para escritura, chronyd no busca un enlace simbólico existente con el mismo nombre de archivo. • https://bugzilla.redhat.com/show_bug.cgi?id=1870298 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6WKABKNLCSC3MACCWU6OM2YGWVWFWFMU https://security.gentoo.org/glsa/202008-23 https://usn.ubuntu.com/4475-1 • CWE-59: Improper Link Resolution Before File Access ('Link Following') •

https://notcve.org/view.php?id=CVE-2020-14350
It was found that some PostgreSQL extensions did not use search_path safely in their installation script. An attacker with sufficient privileges could use this flaw to trick an administrator into executing a specially crafted script, during the installation or update of such extension. This affects PostgreSQL versions before 12.4, before 11.9, before 10.14, before 9.6.19, and before 9.5.23. Se detectó que algunas extensiones de PostgreSQL no usaban la función search_path de forma segura en su script de instalación. Un atacante con suficientes privilegios podría usar este fallo para engañar a un administrador para ejecutar un script especialmente diseñado durante la instalación o actualización de dicha extensión. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00043.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00049.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00050.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00008.html https://bugzilla.redhat.com/show_bug.cgi?id=1865746 https: • CWE-20: Improper Input Validation CWE-426: Untrusted Search Path •
