| CVE-2017-5753 | 13 Arm, Canonical, Debian and 10 more | 387 Cortex-a12, Cortex-a12 Firmware, Cortex-a15 and 384 more | 2021-11-23 | 4.7 MEDIUM | 5.6 MEDIUM |
| Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. | |||||
| CVE-2021-3939 | 1 Canonical | 2 Accountsservice, Ubuntu Linux | 2021-11-19 | 7.2 HIGH | 7.8 HIGH |
| Ubuntu-specific modifications to accountsservice (in patch file debian/patches/0010-set-language.patch) caused the fallback_locale variable, pointing to static storage, to be freed, in the user_change_language_authorized_cb function. This is reachable via the SetLanguage dbus function. This is fixed in versions 0.6.55-0ubuntu12~20.04.5, 0.6.55-0ubuntu13.3, 0.6.55-0ubuntu14.1. | |||||
| CVE-2020-16120 | 2 Canonical, Linux | 2 Ubuntu Linux, Linux Kernel | 2021-11-18 | 2.1 LOW | 4.4 MEDIUM |
| Overlayfs did not properly perform permission checking when copying up files in an overlayfs and could be exploited from within a user namespace, if, for example, unprivileged user namespaces were allowed. It was possible to have a file not readable by an unprivileged user to be copied to a mountpoint controlled by the user, like a removable device. This was introduced in kernel version 4.19 by commit d1d04ef ("ovl: stack file ops"). This was fixed in kernel version 5.8 by commits 56230d9 ("ovl: verify permissions in ovl_path_open()"), 48bd024 ("ovl: switch to mounter creds in readdir") and 05acefb ("ovl: check permission to open real file"). Additionally, commits 130fdbc ("ovl: pass correct flags for opening real directory") and 292f902 ("ovl: call secutiry hook in ovl_real_ioctl()") in kernel 5.8 might also be desired or necessary. These additional commits introduced a regression in overlay mounts within user namespaces which prevented access to files with ownership outside of the user namespace. This regression was mitigated by subsequent commit b6650da ("ovl: do not fail because of O_NOATIMEi") in kernel 5.11. | |||||
| CVE-2020-15103 | 4 Canonical, Fedoraproject, Freerdp and 1 more | 4 Ubuntu Linux, Fedora, Freerdp and 1 more | 2021-11-18 | 3.5 LOW | 3.5 LOW |
| In FreeRDP less than or equal to 2.1.2, an integer overflow exists due to missing input sanitation in rdpegfx channel. All FreeRDP clients are affected. The input rectangles from the server are not checked against local surface coordinates and blindly accepted. A malicious server can send data that will crash the client later on (invalid length arguments to a `memcpy`) This has been fixed in 2.2.0. As a workaround, stop using command line arguments /gfx, /gfx-h264 and /network:auto | |||||
| CVE-2020-15704 | 1 Canonical | 2 Ppp, Ubuntu Linux | 2021-11-18 | 2.1 LOW | 5.5 MEDIUM |
| The modprobe child process in the ./debian/patches/load_ppp_generic_if_needed patch file incorrectly handled module loading. A local non-root attacker could exploit the MODPROBE_OPTIONS environment variable to read arbitrary root files. Fixed in 2.4.5-5ubuntu1.4, 2.4.5-5.1ubuntu2.3+esm2, 2.4.7-1+2ubuntu1.16.04.3, 2.4.7-2+2ubuntu1.3, 2.4.7-2+4.1ubuntu5.1, 2.4.7-2+4.1ubuntu6. Was ZDI-CAN-11504. | |||||
| CVE-2020-15157 | 3 Canonical, Debian, Linuxfoundation | 3 Ubuntu Linux, Debian Linux, Containerd | 2021-11-18 | 2.6 LOW | 6.1 MEDIUM |
| In containerd (an industry-standard container runtime) before version 1.2.14 there is a credential leaking vulnerability. If a container image manifest in the OCI Image format or Docker Image V2 Schema 2 format includes a URL for the location of a specific image layer (otherwise known as a “foreign layer”), the default containerd resolver will follow that URL to attempt to download it. In v1.2.x but not 1.3.0 or later, the default containerd resolver will provide its authentication credentials if the server where the URL is located presents an HTTP 401 status code along with registry-specific HTTP headers. If an attacker publishes a public image with a manifest that directs one of the layers to be fetched from a web server they control and they trick a user or system into pulling the image, they can obtain the credentials used for pulling that image. In some cases, this may be the user's username and password for the registry. In other cases, this may be the credentials attached to the cloud virtual instance which can grant access to other cloud resources in the account. The default containerd resolver is used by the cri-containerd plugin (which can be used by Kubernetes), the ctr development tool, and other client programs that have explicitly linked against it. This vulnerability has been fixed in containerd 1.2.14. containerd 1.3 and later are not affected. If you are using containerd 1.3 or later, you are not affected. If you are using cri-containerd in the 1.2 series or prior, you should ensure you only pull images from trusted sources. Other container runtimes built on top of containerd but not using the default resolver (such as Docker) are not affected. | |||||
| CVE-2016-4450 | 3 Canonical, Debian, F5 | 3 Ubuntu Linux, Debian Linux, Nginx | 2021-11-10 | 5.0 MEDIUM | 7.5 HIGH |
| os/unix/ngx_files.c in nginx before 1.10.1 and 1.11.x before 1.11.1 allows remote attackers to cause a denial of service (NULL pointer dereference and worker process crash) via a crafted request, involving writing a client request body to a temporary file. | |||||
| CVE-2007-2583 | 3 Canonical, Debian, Oracle | 3 Ubuntu Linux, Debian Linux, Mysql | 2021-11-08 | 4.0 MEDIUM | N/A |
| The in_decimal::set function in item_cmpfunc.cc in MySQL before 5.0.40, and 5.1 before 5.1.18-beta, allows context-dependent attackers to cause a denial of service (crash) via a crafted IF clause that results in a divide-by-zero error and a NULL pointer dereference. | |||||
| CVE-2020-11933 | 1 Canonical | 2 Snapd, Ubuntu Linux | 2021-11-04 | 4.6 MEDIUM | 6.8 MEDIUM |
| cloud-init as managed by snapd on Ubuntu Core 16 and Ubuntu Core 18 devices was run without restrictions on every boot, which a physical attacker could exploit by crafting cloud-init user-data/meta-data via external media to perform arbitrary changes on the device to bypass intended security mechanisms such as full disk encryption. This issue did not affect traditional Ubuntu systems. Fixed in snapd version 2.45.2, revision 8539 and core version 2.45.2, revision 9659. | |||||
| CVE-2019-9506 | 8 Apple, Blackberry, Canonical and 5 more | 274 Iphone Os, Mac Os X, Tvos and 271 more | 2021-11-04 | 4.8 MEDIUM | 8.1 HIGH |
| The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks (aka "KNOB") that can decrypt traffic and inject arbitrary ciphertext without the victim noticing. | |||||
