CVSS: 4.7EPSS: 0%CPEs: 3EXPL: 0CVE-2023-2612 – shiftfs lock unbalance in Ubuntu-specific kernels
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 •
