CVE-2019-11810 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2022-12-02 7.8 HIGH 7.5 HIGH
An issue was discovered in the Linux kernel before 5.0.7. A NULL pointer dereference can occur when megasas_create_frame_pool() fails in megasas_alloc_cmds() in drivers/scsi/megaraid/megaraid_sas_base.c. This causes a Denial of Service, related to a use-after-free.
CVE-2019-7304 1 Canonical 2 Snapd, Ubuntu Linux 2022-11-30 10.0 HIGH 9.8 CRITICAL
Canonical snapd before version 2.37.1 incorrectly performed socket owner validation, allowing an attacker to run arbitrary commands as root. This issue affects: Canonical snapd versions prior to 2.37.1.
CVE-2018-1108 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2022-11-29 4.3 MEDIUM 5.9 MEDIUM
kernel drivers before version 4.17-rc1 are vulnerable to a weakness in the Linux kernel's implementation of random seed data. Programs, early in the boot sequence, could use the data allocated for the seed before it was sufficiently generated.
CVE-2011-3389 9 Canonical, Debian, Google and 6 more 17 Ubuntu Linux, Debian Linux, Chrome and 14 more 2022-11-29 4.3 MEDIUM N/A
The SSL protocol, as used in certain configurations in Microsoft Windows and Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Opera, and other products, encrypts data by using CBC mode with chained initialization vectors, which allows man-in-the-middle attackers to obtain plaintext HTTP headers via a blockwise chosen-boundary attack (BCBA) on an HTTPS session, in conjunction with JavaScript code that uses (1) the HTML5 WebSocket API, (2) the Java URLConnection API, or (3) the Silverlight WebClient API, aka a "BEAST" attack.
CVE-2018-2771 6 Canonical, Debian, Mariadb and 3 more 15 Ubuntu Linux, Debian Linux, Mariadb and 12 more 2022-11-28 3.5 LOW 4.4 MEDIUM
Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Locking). Supported versions that are affected are 5.5.59 and prior, 5.6.39 and prior and 5.7.21 and prior. Difficult to exploit vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. CVSS 3.0 Base Score 4.4 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:H).
CVE-2020-14344 4 Canonical, Fedoraproject, Opensuse and 1 more 4 Ubuntu Linux, Fedora, Leap and 1 more 2022-11-28 4.6 MEDIUM 6.7 MEDIUM
An integer overflow leading to a heap-buffer overflow was found in The X Input Method (XIM) client was implemented in libX11 before version 1.6.10. As per upstream this is security relevant when setuid programs call XIM client functions while running with elevated privileges. No such programs are shipped with Red Hat Enterprise Linux.
CVE-2020-13361 4 Canonical, Debian, Opensuse and 1 more 4 Ubuntu Linux, Debian Linux, Leap and 1 more 2022-11-28 3.3 LOW 3.9 LOW
In QEMU 5.0.0 and earlier, es1370_transfer_audio in hw/audio/es1370.c does not properly validate the frame count, which allows guest OS users to trigger an out-of-bounds access during an es1370_write() operation.
CVE-2020-13362 4 Canonical, Debian, Opensuse and 1 more 4 Ubuntu Linux, Debian Linux, Leap and 1 more 2022-11-28 2.1 LOW 3.2 LOW
In QEMU 5.0.0 and earlier, megasas_lookup_frame in hw/scsi/megasas.c has an out-of-bounds read via a crafted reply_queue_head field from a guest OS user.
CVE-2020-1968 5 Canonical, Debian, Fujitsu and 2 more 25 Ubuntu Linux, Debian Linux, M10-1 and 22 more 2022-11-21 4.3 MEDIUM 3.7 LOW
The Raccoon attack exploits a flaw in the TLS specification which can lead to an attacker being able to compute the pre-master secret in connections which have used a Diffie-Hellman (DH) based ciphersuite. In such a case this would result in the attacker being able to eavesdrop on all encrypted communications sent over that TLS connection. The attack can only be exploited if an implementation re-uses a DH secret across multiple TLS connections. Note that this issue only impacts DH ciphersuites and not ECDH ciphersuites. This issue affects OpenSSL 1.0.2 which is out of support and no longer receiving public updates. OpenSSL 1.1.1 is not vulnerable to this issue. Fixed in OpenSSL 1.0.2w (Affected 1.0.2-1.0.2v).
CVE-2020-25641 5 Canonical, Debian, Linux and 2 more 5 Ubuntu Linux, Debian Linux, Linux Kernel and 2 more 2022-11-21 4.9 MEDIUM 5.5 MEDIUM
A flaw was found in the Linux kernel's implementation of biovecs in versions before 5.9-rc7. A zero-length biovec request issued by the block subsystem could cause the kernel to enter an infinite loop, causing a denial of service. This flaw allows a local attacker with basic privileges to issue requests to a block device, resulting in a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2020-14355 5 Canonical, Debian, Opensuse and 2 more 10 Ubuntu Linux, Debian Linux, Leap and 7 more 2022-11-21 6.5 MEDIUM 6.6 MEDIUM
Multiple buffer overflow vulnerabilities were found in the QUIC image decoding process of the SPICE remote display system, before spice-0.14.2-1. Both the SPICE client (spice-gtk) and server are affected by these flaws. These flaws allow a malicious client or server to send specially crafted messages that, when processed by the QUIC image compression algorithm, result in a process crash or potential code execution.
CVE-2020-12866 3 Canonical, Opensuse, Sane-project 3 Ubuntu Linux, Leap, Sane Backends 2022-11-21 2.7 LOW 5.7 MEDIUM
A NULL pointer dereference in SANE Backends before 1.0.30 allows a malicious device connected to the same local network as the victim to cause a denial of service, GHSL-2020-079.
CVE-2020-12861 3 Canonical, Opensuse, Sane-project 3 Ubuntu Linux, Leap, Sane Backends 2022-11-21 7.9 HIGH 8.8 HIGH
A heap buffer overflow in SANE Backends before 1.0.30 allows a malicious device connected to the same local network as the victim to execute arbitrary code, aka GHSL-2020-080.
CVE-2019-15505 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2022-11-16 10.0 HIGH 9.8 CRITICAL
drivers/media/usb/dvb-usb/technisat-usb2.c in the Linux kernel through 5.2.9 has an out-of-bounds read via crafted USB device traffic (which may be remote via usbip or usbredir).
CVE-2020-14364 6 Canonical, Debian, Fedoraproject and 3 more 7 Ubuntu Linux, Debian Linux, Fedora and 4 more 2022-11-16 4.4 MEDIUM 5.0 MEDIUM
An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU in versions before 5.2.0. This issue occurs while processing USB packets from a guest when USBDevice 'setup_len' exceeds its 'data_buf[4096]' in the do_token_in, do_token_out routines. This flaw allows a guest user to crash the QEMU process, resulting in a denial of service, or the potential execution of arbitrary code with the privileges of the QEMU process on the host.
CVE-2020-7729 3 Canonical, Debian, Gruntjs 3 Ubuntu Linux, Debian Linux, Grunt 2022-11-16 4.6 MEDIUM 7.1 HIGH
The package grunt before 1.3.0 are vulnerable to Arbitrary Code Execution due to the default usage of the function load() instead of its secure replacement safeLoad() of the package js-yaml inside grunt.file.readYAML.
CVE-2020-12888 6 Canonical, Debian, Fedoraproject and 3 more 39 Ubuntu Linux, Debian Linux, Fedora and 36 more 2022-11-14 4.7 MEDIUM 5.3 MEDIUM
The VFIO PCI driver in the Linux kernel through 5.6.13 mishandles attempts to access disabled memory space.
CVE-2020-12762 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2022-11-14 6.8 MEDIUM 7.8 HIGH
json-c through 0.14 has an integer overflow and out-of-bounds write via a large JSON file, as demonstrated by printbuf_memappend.
CVE-2018-12207 8 Canonical, Debian, F5 and 5 more 1533 Ubuntu Linux, Debian Linux, Big-ip Access Policy Manager and 1530 more 2022-11-10 4.9 MEDIUM 6.5 MEDIUM
Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access.
CVE-2022-44544 2 Canonical, Mahara 2 Ubuntu Linux, Mahara 2022-11-09 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.
