CVE-2021-32557 1 Canonical 1 Apport 2024-02-28 3.6 LOW 7.1 HIGH
It was discovered that the process_report() function in data/whoopsie-upload-all allowed arbitrary file writes via symlinks.
CVE-2021-32550 1 Canonical 1 Ubuntu Linux 2024-02-28 2.1 LOW 5.5 MEDIUM
It was discovered that read_file() in apport/hookutils.py would follow symbolic links or open FIFOs. When this function is used by the openjdk-14 package apport hooks, it could expose private data to other local users.
CVE-2021-32547 1 Canonical 1 Ubuntu Linux 2024-02-28 2.1 LOW 5.5 MEDIUM
It was discovered that read_file() in apport/hookutils.py would follow symbolic links or open FIFOs. When this function is used by the openjdk-lts package apport hooks, it could expose private data to other local users.
CVE-2021-25682 1 Canonical 1 Apport 2024-02-28 7.2 HIGH 7.8 HIGH
It was discovered that the get_pid_info() function in data/apport did not properly parse the /proc/pid/status file from the kernel.
CVE-2021-3492 1 Canonical 1 Ubuntu Linux 2024-02-28 7.2 HIGH 7.8 HIGH
Shiftfs, an out-of-tree stacking file system included in Ubuntu Linux kernels, did not properly handle faults occurring during copy_from_user() correctly. These could lead to either a double-free situation or memory not being freed at all. An attacker could use this to cause a denial of service (kernel memory exhaustion) or gain privileges via executing arbitrary code. AKA ZDI-CAN-13562.
CVE-2021-3493 1 Canonical 1 Ubuntu Linux 2024-02-28 7.2 HIGH 7.8 HIGH
The overlayfs implementation in the linux kernel did not properly validate with respect to user namespaces the setting of file capabilities on files in an underlying file system. Due to the combination of unprivileged user namespaces along with a patch carried in the Ubuntu kernel to allow unprivileged overlay mounts, an attacker could use this to gain elevated privileges.
CVE-2021-3491 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2024-02-28 7.2 HIGH 8.8 HIGH
The io_uring subsystem in the Linux kernel allowed the MAX_RW_COUNT limit to be bypassed in the PROVIDE_BUFFERS operation, which led to negative values being usedin mem_rw when reading /proc/<PID>/mem. This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was addressed via commit d1f82808877b ("io_uring: truncate lengths larger than MAX_RW_COUNT on provide buffers") (v5.13-rc1) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. It was introduced in ddf0322db79c ("io_uring: add IORING_OP_PROVIDE_BUFFERS") (v5.7-rc1).
CVE-2020-28040 3 Canonical, Debian, Wordpress 3 Ubuntu Linux, Debian Linux, Wordpress 2024-02-28 4.3 MEDIUM 4.3 MEDIUM
WordPress before 5.5.2 allows CSRF attacks that change a theme's background image.
CVE-2020-16128 1 Canonical 1 Ubuntu Linux 2024-02-28 2.1 LOW 3.8 LOW
The aptdaemon DBus interface disclosed file existence disclosure by setting Terminal/DebconfSocket properties, aka GHSL-2020-192 and GHSL-2020-196. This affected versions prior to 1.1.1+bzr982-0ubuntu34.1, 1.1.1+bzr982-0ubuntu32.3, 1.1.1+bzr982-0ubuntu19.5, 1.1.1+bzr982-0ubuntu14.5.
CVE-2020-15157 3 Canonical, Debian, Linuxfoundation 3 Ubuntu Linux, Debian Linux, Containerd 2024-02-28 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-2020-15708 1 Canonical 1 Ubuntu Linux 2024-02-28 4.6 MEDIUM 7.8 HIGH
Ubuntu's packaging of libvirt in 20.04 LTS created a control socket with world read and write permissions. An attacker could use this to overwrite arbitrary files or execute arbitrary code.
CVE-2020-7069 8 Canonical, Debian, Fedoraproject and 5 more 8 Ubuntu Linux, Debian Linux, Fedora and 5 more 2024-02-28 6.4 MEDIUM 6.5 MEDIUM
In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when AES-CCM mode is used with openssl_encrypt() function with 12 bytes IV, only first 7 bytes of the IV is actually used. This can lead to both decreased security and incorrect encryption data.
CVE-2020-16119 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-02-28 4.6 MEDIUM 7.8 HIGH
Use-after-free vulnerability in the Linux kernel exploitable by a local attacker due to reuse of a DCCP socket with an attached dccps_hc_tx_ccid object as a listener after being released. Fixed in Ubuntu Linux kernel 5.4.0-51.56, 5.3.0-68.63, 4.15.0-121.123, 4.4.0-193.224, 3.13.0.182.191 and 3.2.0-149.196.
CVE-2020-14377 3 Canonical, Dpdk, Opensuse 3 Ubuntu Linux, Data Plane Development Kit, Leap 2024-02-28 3.6 LOW 7.1 HIGH
A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A complete lack of validation of attacker-controlled parameters can lead to a buffer over read. The results of the over read are then written back to the guest virtual machine memory. This vulnerability can be used by an attacker in a virtual machine to read significant amounts of host memory. The highest threat from this vulnerability is to data confidentiality and system availability.
CVE-2020-14378 3 Canonical, Dpdk, Opensuse 3 Ubuntu Linux, Data Plane Development Kit, Leap 2024-02-28 2.1 LOW 3.3 LOW
An integer underflow in dpdk versions before 18.11.10 and before 19.11.5 in the `move_desc` function can lead to large amounts of CPU cycles being eaten up in a long running loop. An attacker could cause `move_desc` to get stuck in a 4,294,967,295-count iteration loop. Depending on how `vhost_crypto` is being used this could prevent other VMs or network tasks from being serviced by the busy DPDK lcore for an extended period.
CVE-2020-25645 5 Canonical, Debian, Linux and 2 more 8 Ubuntu Linux, Debian Linux, Linux Kernel and 5 more 2024-02-28 5.0 MEDIUM 7.5 HIGH
A flaw was found in the Linux kernel in versions before 5.9-rc7. Traffic between two Geneve endpoints may be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE tunnel allowing anyone between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality.
CVE-2020-27349 1 Canonical 1 Ubuntu Linux 2024-02-28 2.1 LOW 5.5 MEDIUM
Aptdaemon performed policykit checks after interacting with potentially untrusted files with elevated privileges. This affected versions prior to 1.1.1+bzr982-0ubuntu34.1, 1.1.1+bzr982-0ubuntu32.3, 1.1.1+bzr982-0ubuntu19.5, 1.1.1+bzr982-0ubuntu14.5.
CVE-2013-1053 1 Canonical 1 Remote-login-service 2024-02-28 2.1 LOW 5.5 MEDIUM
In crypt.c of remote-login-service, the cryptographic algorithm used to cache usernames and passwords is insecure. An attacker could use this vulnerability to recover usernames and passwords from the file. This issue affects version 1.0.0-0ubuntu3 and prior versions.
CVE-2020-26116 7 Canonical, Debian, Fedoraproject and 4 more 9 Ubuntu Linux, Debian Linux, Fedora and 6 more 2024-02-28 6.4 MEDIUM 7.2 HIGH
http.client in Python 3.x before 3.5.10, 3.6.x before 3.6.12, 3.7.x before 3.7.9, and 3.8.x before 3.8.5 allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR and LF control characters in the first argument of HTTPConnection.request.
CVE-2020-14376 3 Canonical, Dpdk, Opensuse 3 Ubuntu Linux, Data Plane Development Kit, Leap 2024-02-28 6.9 MEDIUM 7.8 HIGH
A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A lack of bounds checking when copying iv_data from the VM guest memory into host memory can lead to a large buffer overflow. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
