sysdeps/i386/ldbl2mpn.c in the GNU C Library (aka glibc or libc6) before 2.23 on x86 targets has a stack-based buffer overflow if the input to any of the printf family of functions is an 80-bit long double with a non-canonical bit pattern, as seen when passing a \x00\x04\x00\x00\x00\x00\x00\x00\x00\x04 value to sprintf |

| CVE-2020-29562 | 보통4.8 | The iconv function in the GNU C Library (aka glibc or libc6) 2.30 to 2.32, when converting UCS4 text containing an irreversible character, fails an assertion in the code path and aborts the program, potentially resulting in a denial of service. | 04/12/2020 |
| CVE-1999-0199 | 심각9.8 | manual/search.texi in the GNU C Library (aka glibc) before 2.2 lacks a statement about the unspecified tdelete return value upon deletion of a tree's root, which might allow attackers to access a dangling pointer in an application whose developer was unaware of a documentation update from 1999. | 06/10/2020 |
| CVE-2020-24659 | 높음7.5 | An issue was discovered in GnuTLS before 3.6.15. A server can trigger a NULL pointer dereference in a TLS 1.3 client if a no_renegotiation alert is sent with unexpected timing, and then an invalid second handshake occurs. The crash happens in the application's error handling path, where the gnutls_deinit function is ca | 04/09/2020 |
| CVE-2020-24240 | 보통5.5 | GNU Bison before 3.7.1 has a use-after-free in _obstack_free in lib/obstack.c (called from gram_lex) when a '\0' byte is encountered. NOTE: there is a risk only if Bison is used with untrusted input, and the observed bug happens to cause unsafe behavior with a specific compiler/architecture. The bug report was intended | 25/08/2020 |
| CVE-2020-14311 | 보통6.0 | 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. | 31/07/2020 |
| CVE-2020-14310 | 보통6.0 | 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 wh | 31/07/2020 |
| CVE-2020-14309 | 보통6.7 | 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. | 30/07/2020 |
| CVE-2020-10713 | 높음8.2 | A flaw was found in grub2, prior to version 2.06. An attacker may use the GRUB 2 flaw to hijack and tamper the GRUB verification process. This flaw also allows the bypass of Secure Boot protections. In order to load an untrusted or modified kernel, an attacker would first need to establish access to the system such as | 30/07/2020 |
| CVE-2020-14308 | 보통6.4 | In grub2 versions before 2.06 the grub memory allocator doesn't check for possible arithmetic overflows on the requested allocation size. This leads the function to return invalid memory allocations which can be further used to cause possible integrity, confidentiality and availability impacts during the boot process. | 29/07/2020 |
| CVE-2020-15707 | 보통6.4 | 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 a | 29/07/2020 |
| CVE-2020-15706 | 보통6.4 | 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 prio | 29/07/2020 |
| CVE-2020-15705 | 보통6.4 | 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 | 29/07/2020 |
| CVE-2020-15807 | 보통6.5 | GNU LibreDWG before 0.11 allows NULL pointer dereferences via crafted input files. | 17/07/2020 |
| CVE-2019-20915 | 높음8.1 | An issue was discovered in GNU LibreDWG through 0.9.3. Crafted input will lead to a heap-based buffer over-read in bit_write_TF in bits.c. | 16/07/2020 |
| CVE-2019-20914 | 심각9.8 | An issue was discovered in GNU LibreDWG through 0.9.3. There is a NULL pointer dereference in the function dwg_encode_common_entity_handle_data in common_entity_handle_data.spec. | 16/07/2020 |
| CVE-2019-20913 | 높음8.1 | An issue was discovered in GNU LibreDWG through 0.9.3. Crafted input will lead to a heap-based buffer over-read in dwg_encode_entity in common_entity_data.spec. | 16/07/2020 |
