CVE-2020-14339 (GCVE-0-2020-14339)
Vulnerability from – Published: 2020-12-03 00:00 – Updated: 2024-08-04 12:39
VLAI?
Summary
A flaw was found in libvirt, where it leaked a file descriptor for `/dev/mapper/control` into the QEMU process. This file descriptor allows for privileged operations to happen against the device-mapper on the host. This flaw allows a malicious guest user or process to perform operations outside of their standard permissions, potentially causing serious damage to the host operating system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
Severity ?
No CVSS data available.

CVE-2020-14331 (GCVE-0-2020-14331)
Vulnerability from – Published: 2020-09-15 18:51 – Updated: 2024-08-04 12:39
VLAI?
Summary
A flaw was found in the Linux kernel’s implementation of the invert video code on VGA consoles when a local attacker attempts to resize the console, calling an ioctl VT_RESIZE, which causes an out-of-bounds write to occur. This flaw allows a local user with access to the VGA console to crash the system, potentially escalating their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
Severity ?
No CVSS data available.

CVE-2020-14310 (GCVE-0-2020-14310)
Vulnerability from – Published: 2020-07-31 20:55 – Updated: 2024-08-04 12:39
VLAI?
Summary
There is an issue on grub2 before version 2.06 at function read_section_as_string(). It expects a font name to be at max UINT32_MAX - 1 length in bytes but it doesn't verify it before proceed with buffer allocation to read the value from the font value. An attacker may leverage that by crafting a malicious font file which has a name with UINT32_MAX, leading to read_section_as_string() to an arithmetic overflow, zero-sized allocation and further heap-based buffer overflow.
Severity ?
5.7 (Medium)

CVE-2020-12826 (GCVE-0-2020-12826)
Vulnerability from – Published: 2020-05-12 18:58 – Updated: 2024-08-04 12:04
VLAI?
Summary
A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2. Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in a different security domain. Exploitation limitations include the amount of elapsed time before an integer overflow occurs, and the lack of scenarios where signals to a parent process present a substantial operational threat.
Severity ?
No CVSS data available.

Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in a different security domain. Exploitation limitations include the amount of elapsed time before an integer overflow occurs, and the lack of scenarios where signals to a parent process present a substantial operational threat."

CVE-2020-12430 (GCVE-0-2020-12430)
Vulnerability from – Published: 2020-04-28 00:00 – Updated: 2024-08-04 11:56
VLAI?
Summary
An issue was discovered in qemuDomainGetStatsIOThread in qemu/qemu_driver.c in libvirt 4.10.0 though 6.x before 6.1.0. A memory leak was found in the virDomainListGetStats libvirt API that is responsible for retrieving domain statistics when managing QEMU guests. This flaw allows unprivileged users with a read-only connection to cause a memory leak in the domstats command, resulting in a potential denial of service.
Severity ?
