CVE-2020-16591 2 Gnu, Netapp 2 Binutils, Ontap Select Deploy Administration Utility 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
A Denial of Service vulnerability exists in the Binary File Descriptor (BFD) in GNU Binutils 2.35 due to an invalid read in process_symbol_table, as demonstrated in readeif.
CVE-2020-16590 2 Gnu, Netapp 2 Binutils, Ontap Select Deploy Administration Utility 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
A double free vulnerability exists in the Binary File Descriptor (BFD) (aka libbrd) in GNU Binutils 2.35 in the process_symbol_table, as demonstrated in readelf, via a crafted file.
CVE-2020-15807 1 Gnu 1 Libredwg 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
GNU LibreDWG before 0.11 allows NULL pointer dereferences via crafted input files.
CVE-2020-15707 8 Canonical, Debian, Gnu and 5 more 15 Ubuntu Linux, Debian Linux, Grub2 and 12 more 2024-11-21 4.4 MEDIUM 5.7 MEDIUM
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 and bypass UEFI Secure Boot restrictions. This issue affects GRUB2 version 2.04 and prior versions.
CVE-2020-15706 7 Canonical, Debian, Gnu and 4 more 14 Ubuntu Linux, Debian Linux, Grub2 and 11 more 2024-11-21 4.4 MEDIUM 6.4 MEDIUM
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.
CVE-2020-15705 7 Canonical, Debian, Gnu and 4 more 14 Ubuntu Linux, Debian Linux, Grub2 and 11 more 2024-11-21 4.4 MEDIUM 6.4 MEDIUM
GRUB2 fails to validate kernel signature when booted directly without shim, allowing secure boot to be bypassed. This only affects systems where the kernel signing certificate has been imported directly into the secure boot database and the GRUB image is booted directly without the use of shim. This issue affects GRUB2 version 2.04 and prior versions.
CVE-2020-15011 3 Canonical, Debian, Gnu 3 Ubuntu Linux, Debian Linux, Mailman 2024-11-21 2.6 LOW 4.3 MEDIUM
GNU Mailman before 2.1.33 allows arbitrary content injection via the Cgi/private.py private archive login page.
CVE-2020-14372 4 Fedoraproject, Gnu, Netapp and 1 more 9 Fedora, Grub2, Cloud Backup and 6 more 2024-11-21 6.2 MEDIUM 7.5 HIGH
A flaw was found in grub2 in versions prior to 2.06, where it incorrectly enables the usage of the ACPI command when Secure Boot is enabled. This flaw allows an attacker with privileged access to craft a Secondary System Description Table (SSDT) containing code to overwrite the Linux kernel lockdown variable content directly into memory. The table is further loaded and executed by the kernel, defeating its Secure Boot lockdown and allowing the attacker to load unsigned code. The highest threat from this vulnerability is to data confidentiality and integrity, as well as system availability.
CVE-2020-14311 4 Canonical, Gnu, Opensuse and 1 more 7 Ubuntu Linux, Grub2, Leap and 4 more 2024-11-21 3.6 LOW 5.7 MEDIUM
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.
CVE-2020-14310 4 Canonical, Gnu, Opensuse and 1 more 7 Ubuntu Linux, Grub2, Leap and 4 more 2024-11-21 3.6 LOW 5.7 MEDIUM
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.
CVE-2020-14309 2 Gnu, Opensuse 2 Grub2, Leap 2024-11-21 4.6 MEDIUM 6.7 MEDIUM
There's an issue with grub2 in all versions before 2.06 when handling squashfs filesystems containing a symbolic link with name length of UINT32 bytes in size. The name size leads to an arithmetic overflow leading to a zero-size allocation further causing a heap-based buffer overflow with attacker controlled data.
