CVE-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 •
CVE-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 •
CVE-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 •
CVE-2023-1380
https://notcve.org/view.php?id=CVE-2023-1380
A slab-out-of-bound read problem was found in brcmf_get_assoc_ies in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux Kernel. This issue could occur when assoc_info->req_len data is bigger than the size of the buffer, defined as WL_EXTRA_BUF_MAX, leading to a denial of service. • http://packetstormsecurity.com/files/173087/Kernel-Live-Patch-Security-Notice-LSN-0095-1.html http://packetstormsecurity.com/files/173757/Kernel-Live-Patch-Security-Notice-LSN-0096-1.html https://bugzilla.redhat.com/show_bug.cgi?id=2177883 https://lists.debian.org/debian-lts-announce/2023/07/msg00030.html https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://lore.kernel.org/linux-wireless/20230309104457.22628-1-jisoo.jang%40yonsei.ac.kr/T/#u https://security.netapp.com& • CWE-125: Out-of-bounds Read •
CVE-2023-0179 – kernel: Netfilter integer overflow vulnerability in nft_payload_copy_vlan
https://notcve.org/view.php?id=CVE-2023-0179
A buffer overflow vulnerability was found in the Netfilter subsystem in the Linux Kernel. This issue could allow the leakage of both stack and heap addresses, and potentially allow Local Privilege Escalation to the root user via arbitrary code execution. • https://github.com/TurtleARM/CVE-2023-0179-PoC https://github.com/H4K6/CVE-2023-0179-PoC http://packetstormsecurity.com/files/171601/Kernel-Live-Patch-Security-Notice-LNS-0093-1.html https://bugzilla.redhat.com/show_bug.cgi?id=2161713 https://seclists.org/oss-sec/2023/q1/20 https://security.netapp.com/advisory/ntap-20230511-0003 https://access.redhat.com/security/cve/CVE-2023-0179 • CWE-190: Integer Overflow or Wraparound •
