| 2020-07-29 | CVE-2020-15706 | GRUB2 contains a race condition in grub_script_function_create() leading to a use-after-free vulnerability which can be triggered by redefining a function whilst the same function is already executing, leading to arbitrary code execution and secure boot restriction bypass. This issue affects GRUB2 version 2.04 and prior versions. | Ubuntu_linux, Debian_linux, Grub2, Windows_10, Windows_8\.1, Windows_rt_8\.1, Windows_server_2012, Windows_server_2016, Windows_server_2019, Leap, Enterprise_linux, Enterprise_linux_atomic_host, Openshift_container_platform, Suse_linux_enterprise_server | 6.4 | ||
| 2020-07-29 | CVE-2020-15707 | Integer overflows were discovered in the functions grub_cmd_initrd and grub_initrd_init in the efilinux component of GRUB2, as shipped in Debian, Red Hat, and Ubuntu (the functionality is not included in GRUB2 upstream), leading to a heap-based buffer overflow. These could be triggered by an extremely large number of arguments to the initrd command on 32-bit architectures, or a crafted filesystem with very large files on any architecture. An attacker could use this to execute arbitrary code... | Ubuntu_linux, Debian_linux, Grub2, Windows_10, Windows_8\.1, Windows_rt_8\.1, Windows_server_2012, Windows_server_2016, Windows_server_2019, Active_iq_unified_manager, Leap, Enterprise_linux, Enterprise_linux_atomic_host, Openshift_container_platform, Suse_linux_enterprise_server | 6.4 | ||
| 2020-07-29 | CVE-2020-16135 | libssh 0.9.4 has a NULL pointer dereference in tftpserver.c if ssh_buffer_new returns NULL. | Ubuntu_linux, Debian_linux, Fedora, Libssh, Communications_cloud_native_core_policy | 5.9 | ||
| 2020-07-30 | CVE-2020-16166 | The Linux kernel through 5.7.11 allows remote attackers to make observations that help to obtain sensitive information about the internal state of the network RNG, aka CID-f227e3ec3b5c. This is related to drivers/char/random.c and kernel/time/timer.c. | Ubuntu_linux, Debian_linux, Fedora, Linux_kernel, Active_iq_unified_manager, Cloud_volumes_ontap_mediator, E\-Series_santricity_os_controller, H410c_firmware, Hci_bootstrap_os, Hci_management_node, Solidfire, Steelstore_cloud_integrated_storage, Storagegrid, Leap, Sd\-Wan_edge | 3.7 | ||
| 2020-07-31 | CVE-2020-14310 | 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. | Ubuntu_linux, Grub2, Leap, Enterprise_linux, Enterprise_linux_eus, Enterprise_linux_server_aus, Enterprise_linux_server_tus | 6.0 | ||
| 2020-07-31 | CVE-2020-14311 | There is an issue with grub2 before version 2.06 while handling symlink on ext filesystems. A filesystem containing a symbolic link with an inode size of UINT32_MAX causes an arithmetic overflow leading to a zero-sized memory allocation with subsequent heap-based buffer overflow. | Ubuntu_linux, Grub2, Leap, Enterprise_linux, Enterprise_linux_eus, Enterprise_linux_server_aus, Enterprise_linux_server_tus | 6.0 | ||
| 2020-08-03 | CVE-2020-16116 | In kerfuffle/jobs.cpp in KDE Ark before 20.08.0, a crafted archive can install files outside the extraction directory via ../ directory traversal. | Ubuntu_linux, Debian_linux, Fedora, Ark, Leap | 3.3 | ||
| 2020-08-05 | CVE-2020-14344 | 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. | Ubuntu_linux, Fedora, Leap, Libx11 | 6.7 | ||
| 2020-08-05 | CVE-2020-14347 | A flaw was found in the way xserver memory was not properly initialized. This could leak parts of server memory to the X client. In cases where Xorg server runs with elevated privileges, this could result in possible ASLR bypass. Xorg-server before version 1.20.9 is vulnerable. | Ubuntu_linux, Debian_linux, Xorg\-Server | 5.5 | ||
| 2020-08-06 | CVE-2020-15702 | TOCTOU Race Condition vulnerability in apport allows a local attacker to escalate privileges and execute arbitrary code. An attacker may exit the crashed process and exploit PID recycling to spawn a root process with the same PID as the crashed process, which can then be used to escalate privileges. Fixed in 2.20.1-0ubuntu2.24, 2.20.9 versions prior to 2.20.9-0ubuntu7.16 and 2.20.11 versions prior to 2.20.11-0ubuntu27.6. Was ZDI-CAN-11234. | Apport, Ubuntu_linux | 7.0 |
