https://notcve.org/view.php?id=CVE-2023-35788
An issue was discovered in fl_set_geneve_opt in net/sched/cls_flower.c in the Linux kernel before 6.3.7. It allows an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets. This may result in denial of service or privilege escalation. Se descubrió un problema en fl_set_geneve_opt en net/sched/cls_flower.c en el kernel de Linux antes de 6.3.7. Permite una escritura fuera de los límites en el código flower classifier a través de paquetes TCA_FLOWER_KEY_ENC_OPTS_GENEVE. • http://packetstormsecurity.com/files/174577/Kernel-Live-Patch-Security-Notice-LSN-0097-1.html http://www.openwall.com/lists/oss-security/2023/06/17/1 https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.3.7 https://git.kernel.org/linus/4d56304e5827c8cc8cc18c75343d283af7c4825c https://lists.debian.org/debian-lts-announce/2023/07/msg00030.html https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://security.netapp.com/advisory/ntap-20230714-0002 https://www.debian& • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2023-1523
Using the TIOCLINUX ioctl request, a malicious snap could inject contents into the input of the controlling terminal which could allow it to cause arbitrary commands to be executed outside of the snap sandbox after the snap exits. Graphical terminal emulators like xterm, gnome-terminal and others are not affected - this can only be exploited when snaps are run on a virtual console. Utilizando la petición IOCTL de TIOCLINUX, un snap malicoso podría inyectar contenido en la entrada del terminal de control, lo que podría permitir que se ejecutaran comandos arbitrarios fuera del sandbox del snap después de que éste saliera. Los emuladores gráficos de terminal como xterm, gnome-terminal y otros no se ven afectados. Esto sólo puede ser explotado cuando los snaps se ejecutan en una consola virtual. • https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-1523 https://github.com/snapcore/snapd/pull/12849 https://marc.info/?l=oss-security&m=167879021709955&w=2 https://ubuntu.com/security/notices/USN-6125-1 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •

https://notcve.org/view.php?id=CVE-2023-2612
Jean-Baptiste Cayrou discovered that the shiftfs file system in the Ubuntu Linux kernel contained a race condition when handling inode locking in some situations. A local attacker could use this to cause a denial of service (kernel deadlock). • http://packetstormsecurity.com/files/173087/Kernel-Live-Patch-Security-Notice-LSN-0095-1.html https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/kinetic/commit/?id=02b47547824b1cd0d55c6744f91886f04de8947e https://ubuntu.com/security/CVE-2023-2612 https://ubuntu.com/security/notices/USN-6122-1 https://ubuntu.com/security/notices/USN-6123-1 https://ubuntu.com/security/notices/USN-6124-1 https://ubuntu.com/security/notices/USN-6127-1 • CWE-667: Improper Locking •
CVSS: 5.5EPSS: 0%CPEs: 8EXPL: 0CVE-2023-1786 – sensitive data exposure in cloud-init logs
https://notcve.org/view.php?id=CVE-2023-1786
Sensitive data could be exposed in logs of cloud-init before version 23.1.2. An attacker could use this information to find hashed passwords and possibly escalate their privilege. A vulnerability was found in cloud-init. With this flaw, exposure of sensitive data is possible in world-readable cloud-init logs. This flaw allows an attacker to use this information to find hashed passwords and possibly escalate their privilege. • https://bugs.launchpad.net/cloud-init/+bug/2013967 https://github.com/canonical/cloud-init/commit/a378b7e4f47375458651c0972e7cd813f6fe0a6b https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/ATBJSXPL2IOAD2LDQRKWPLIC7QXS44GZ https://ubuntu.com/security/notices/USN-6042-1 https://access.redhat.com/security/cve/CVE-2023-1786 https://bugzilla.redhat.com/show_bug.cgi?id=2190079 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-532: Insertion of Sensitive Information into Log File •
CVSS: 7.8EPSS: 0%CPEs: 5EXPL: 4CVE-2023-1326 – local privilege escalation in apport-cli
https://notcve.org/view.php?id=CVE-2023-1326
A privilege escalation attack was found in apport-cli 2.26.0 and earlier which is similar to CVE-2023-26604. If a system is specially configured to allow unprivileged users to run sudo apport-cli, less is configured as the pager, and the terminal size can be set: a local attacker can escalate privilege. It is extremely unlikely that a system administrator would configure sudo to allow unprivileged users to perform this class of exploit. • https://github.com/diego-tella/CVE-2023-1326-PoC https://github.com/cve-2024/CVE-2023-1326-PoC https://github.com/Pol-Ruiz/CVE-2023-1326 https://github.com/N3rdyN3xus/CVE-2023-1326 https://github.com/canonical/apport/commit/e5f78cc89f1f5888b6a56b785dddcb0364c48ecb https://ubuntu.com/security/notices/USN-6018-1 • CWE-269: Improper Privilege Management •
