CVE-2023-1523 1 Canonical 2 Snapd, Ubuntu Linux 2023-12-10 N/A 10.0 CRITICAL
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.
CVE-2023-44216 7 Amd, Apple, Canonical and 4 more 16 Ryzen 5 7600x, Ryzen 7 4800u, M1 Mac Mini and 13 more 2023-12-10 N/A 5.3 MEDIUM
PVRIC (PowerVR Image Compression) on Imagination 2018 and later GPU devices offers software-transparent compression that enables cross-origin pixel-stealing attacks against feTurbulence and feBlend in the SVG Filter specification, aka a GPU.zip issue. For example, attackers can sometimes accurately determine text contained on a web page from one origin if they control a resource from a different origin.
CVE-2023-31021 7 Canonical, Citrix, Linux-kvm and 4 more 7 Ubuntu Linux, Hypervisor, Kernel Virtual Machine and 4 more 2023-12-10 N/A 5.5 MEDIUM
NVIDIA vGPU software for Windows and Linux contains a vulnerability in the Virtual GPU Manager (vGPU plugin), where a malicious user in the guest VM can cause a NULL-pointer dereference, which may lead to denial of service.
CVE-2023-31018 8 Canonical, Citrix, Linux and 5 more 9 Ubuntu Linux, Hypervisor, Linux Kernel and 6 more 2023-12-10 N/A 5.5 MEDIUM
NVIDIA GPU Driver for Windows and Linux contains a vulnerability in the kernel mode layer, where an unprivileged regular user can cause a NULL-pointer dereference, which may lead to denial of service.
CVE-2023-2640 1 Canonical 1 Ubuntu Linux 2023-12-10 N/A 7.8 HIGH
On Ubuntu kernels carrying both c914c0e27eb0 and "UBUNTU: SAUCE: overlayfs: Skip permission checking for trusted.overlayfs.* xattrs", an unprivileged user may set privileged extended attributes on the mounted files, leading them to be set on the upper files without the appropriate security checks.
CVE-2023-1326 1 Canonical 2 Apport, Ubuntu Linux 2023-12-10 N/A 7.8 HIGH
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.
CVE-2023-2612 1 Canonical 1 Ubuntu Linux 2023-12-10 N/A 4.7 MEDIUM
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).
CVE-2023-0179 4 Canonical, Fedoraproject, Linux and 1 more 14 Ubuntu Linux, Fedora, Linux Kernel and 11 more 2023-12-10 N/A 7.8 HIGH
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.
CVE-2022-2084 1 Canonical 2 Cloud-init, Ubuntu Linux 2023-12-10 N/A 5.5 MEDIUM
Sensitive data could be exposed in world readable logs of cloud-init before version 22.3 when schema failures are reported. This leak could include hashed passwords.
CVE-2023-24492 2 Canonical, Citrix 2 Ubuntu Linux, Secure Access Client 2023-12-10 N/A 8.8 HIGH
A vulnerability has been discovered in the Citrix Secure Access client for Ubuntu which, if exploited, could allow an attacker to remotely execute code if a victim user opens an attacker-crafted link and accepts further prompts.
CVE-2023-1786 2 Canonical, Fedoraproject 3 Cloud-init, Ubuntu Linux, Fedora 2023-12-10 N/A 5.5 MEDIUM
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.
CVE-2023-35788 4 Canonical, Debian, Linux and 1 more 13 Ubuntu Linux, Debian Linux, Linux Kernel and 10 more 2023-12-10 N/A 7.8 HIGH
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.
CVE-2023-3389 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2023-12-10 N/A 7.8 HIGH
A use-after-free vulnerability in the Linux Kernel io_uring subsystem can be exploited to achieve local privilege escalation. Racing a io_uring cancel poll request with a linked timeout can cause a UAF in a hrtimer. We recommend upgrading past commit ef7dfac51d8ed961b742218f526bd589f3900a59 (4716c73b188566865bdd79c3a6709696a224ac04 for 5.10 stable and 0e388fce7aec40992eadee654193cad345d62663 for 5.15 stable).
CVE-2023-1380 5 Canonical, Debian, Linux and 2 more 14 Ubuntu Linux, Debian Linux, Linux Kernel and 11 more 2023-12-10 N/A 7.1 HIGH
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.
CVE-2021-3905 4 Canonical, Fedoraproject, Openvswitch and 1 more 4 Ubuntu Linux, Fedora, Openvswitch and 1 more 2023-12-10 N/A 7.5 HIGH
A memory leak was found in Open vSwitch (OVS) during userspace IP fragmentation processing. An attacker could use this flaw to potentially exhaust available memory by keeping sending packet fragments.
CVE-2022-44544 2 Canonical, Mahara 2 Ubuntu Linux, Mahara 2023-12-10 N/A 9.8 CRITICAL
Mahara 21.04 before 21.04.7, 21.10 before 21.10.5, 22.04 before 22.04.3, and 22.10 before 22.10.0 potentially allow a PDF export to trigger a remote shell if the site is running on Ubuntu and the flag -dSAFER is not set with Ghostscript.
CVE-2022-40277 3 Canonical, Joplinapp, Linux 3 Ubuntu Linux, Joplin, Linux Kernel 2023-12-10 N/A 7.8 HIGH
Joplin version 2.8.8 allows an external attacker to execute arbitrary commands remotely on any client that opens a link in a malicious markdown file, via Joplin. This is possible because the application does not properly validate the schema/protocol of existing links in the markdown file before passing them to the 'shell.openExternal' function.
CVE-2022-34918 4 Canonical, Debian, Linux and 1 more 13 Ubuntu Linux, Debian Linux, Linux Kernel and 10 more 2023-12-10 7.2 HIGH 7.8 HIGH
An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data in net/netfilter/nf_tables_api.c.
CVE-2022-39177 3 Bluez, Canonical, Debian 3 Bluez, Ubuntu Linux, Debian Linux 2023-12-10 N/A 8.8 HIGH
BlueZ before 5.59 allows physically proximate attackers to cause a denial of service because malformed and invalid capabilities can be processed in profiles/audio/avdtp.c.
CVE-2022-39176 3 Bluez, Canonical, Debian 3 Bluez, Ubuntu Linux, Debian Linux 2023-12-10 N/A 8.8 HIGH
BlueZ before 5.59 allows physically proximate attackers to obtain sensitive information because profiles/audio/avrcp.c does not validate params_len.
