CVE-2021-20225 4 Fedoraproject, Gnu, Netapp and 1 more 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more 2026-06-17 7.2 HIGH 6.7 MEDIUM
A flaw was found in grub2 in versions prior to 2.06. The option parser allows an attacker to write past the end of a heap-allocated buffer by calling certain commands with a large number of specific short forms of options. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2021-20197 4 Broadcom, Gnu, Netapp and 1 more 6 Brocade Fabric Operating System Firmware, Binutils, Cloud Backup and 3 more 2026-06-17 3.3 LOW 6.3 MEDIUM
There is an open race window when writing output in the following utilities in GNU binutils version 2.35 and earlier:ar, objcopy, strip, ranlib. When these utilities are run as a privileged user (presumably as part of a script updating binaries across different users), an unprivileged user can trick these utilities into getting ownership of arbitrary files through a symlink.
CVE-2020-9366 1 Gnu 1 Screen 2026-06-17 7.5 HIGH 9.8 CRITICAL
A buffer overflow was found in the way GNU Screen before 4.8.0 treated the special escape OSC 49. Specially crafted output, or a special program, could corrupt memory and crash Screen or possibly have unspecified other impact.
CVE-2020-6615 2 Gnu, Opensuse 3 Libredwg, Backports Sle, Leap 2026-06-17 4.3 MEDIUM 6.5 MEDIUM
GNU LibreDWG 0.9.3.2564 has an invalid pointer dereference in dwg_dynapi_entity_value in dynapi.c (dynapi.c is generated by gen-dynapi.pl).
CVE-2020-6614 2 Gnu, Opensuse 3 Libredwg, Backports Sle, Leap 2026-06-17 5.8 MEDIUM 8.1 HIGH
GNU LibreDWG 0.9.3.2564 has a heap-based buffer over-read in bfr_read in decode.c.
CVE-2020-6613 2 Gnu, Opensuse 3 Libredwg, Backports Sle, Leap 2026-06-17 5.8 MEDIUM 8.1 HIGH
GNU LibreDWG 0.9.3.2564 has a heap-based buffer over-read in bit_search_sentinel in bits.c.
CVE-2020-6612 2 Gnu, Opensuse 3 Libredwg, Backports Sle, Leap 2026-06-17 5.8 MEDIUM 8.1 HIGH
GNU LibreDWG 0.9.3.2564 has a heap-based buffer over-read in copy_compressed_bytes in decode_r2007.c.
CVE-2020-6611 2 Gnu, Opensuse 3 Libredwg, Backports Sle, Leap 2026-06-17 4.3 MEDIUM 6.5 MEDIUM
GNU LibreDWG 0.9.3.2564 has a NULL pointer dereference in get_next_owned_entity in dwg.c.
CVE-2020-6610 2 Gnu, Opensuse 3 Libredwg, Backports, Leap 2026-06-17 4.3 MEDIUM 6.5 MEDIUM
GNU LibreDWG 0.9.3.2564 has an attempted excessive memory allocation in read_sections_map in decode_r2007.c.
CVE-2020-6609 2 Gnu, Opensuse 3 Libredwg, Backports Sle, Leap 2026-06-17 6.8 MEDIUM 8.8 HIGH
GNU LibreDWG 0.9.3.2564 has a heap-based buffer over-read in read_pages_map in decode_r2007.c.
CVE-2020-35448 2 Gnu, Netapp 2 Binutils, Ontap Select Deploy Administration Utility 2026-06-17 4.3 MEDIUM 3.3 LOW
An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.35.1. A heap-based buffer over-read can occur in bfd_getl_signed_32 in libbfd.c because sh_entsize is not validated in _bfd_elf_slurp_secondary_reloc_section in elf.c.
CVE-2020-35357 2 Debian, Gnu 2 Debian Linux, Gnu Scientific Library 2026-06-17 N/A 6.5 MEDIUM
A buffer overflow can occur when calculating the quantile value using the Statistics Library of GSL (GNU Scientific Library), versions 2.5 and 2.6. Processing a maliciously crafted input data for gsl_stats_quantile_from_sorted_data of the library may lead to unexpected application termination or arbitrary code execution.
CVE-2020-35342 1 Gnu 1 Binutils 2026-06-17 N/A 7.5 HIGH
GNU Binutils before 2.34 has an uninitialized-heap vulnerability in function tic4x_print_cond (file opcodes/tic4x-dis.c) which could allow attackers to make an information leak.
CVE-2020-27779 4 Fedoraproject, Gnu, Netapp and 1 more 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more 2026-06-17 6.9 MEDIUM 7.5 HIGH
A flaw was found in grub2 in versions prior to 2.06. The cutmem command does not honor secure boot locking allowing an privileged attacker to remove address ranges from memory creating an opportunity to circumvent SecureBoot protections after proper triage about grub's memory layout. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-27749 4 Fedoraproject, Gnu, Netapp and 1 more 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more 2026-06-17 7.2 HIGH 6.7 MEDIUM
A flaw was found in grub2 in versions prior to 2.06. Variable names present are expanded in the supplied command line into their corresponding variable contents, using a 1kB stack buffer for temporary storage, without sufficient bounds checking. If the function is called with a command line that references a variable with a sufficiently large payload, it is possible to overflow the stack buffer, corrupt the stack frame and control execution which could also circumvent Secure Boot protections. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-25647 4 Fedoraproject, Gnu, Netapp and 1 more 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more 2026-06-17 7.2 HIGH 7.6 HIGH
A flaw was found in grub2 in versions prior to 2.06. During USB device initialization, descriptors are read with very little bounds checking and assumes the USB device is providing sane values. If properly exploited, an attacker could trigger memory corruption leading to arbitrary code execution allowing a bypass of the Secure Boot mechanism. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-25632 4 Fedoraproject, Gnu, Netapp and 1 more 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more 2026-06-17 7.2 HIGH 8.2 HIGH
A flaw was found in grub2 in versions prior to 2.06. The rmmod implementation allows the unloading of a module used as a dependency without checking if any other dependent module is still loaded leading to a use-after-free scenario. This could allow arbitrary code to be executed or a bypass of Secure Boot protections. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-24240 1 Gnu 1 Bison 2026-06-17 7.1 HIGH 5.5 MEDIUM
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 to show that a crash may occur in Bison itself, not that a crash may occur in code that is generated by Bison.
CVE-2020-23861 1 Gnu 1 Libredwg 2026-06-17 4.3 MEDIUM 5.5 MEDIUM
A heap-based buffer overflow vulnerability exists in LibreDWG 0.10.1 via the read_system_page function at libredwg-0.10.1/src/decode_r2007.c:666:5, which causes a denial of service by submitting a dwg file.
CVE-2020-23856 2 Fedoraproject, Gnu 2 Fedora, Cflow 2026-06-17 2.1 LOW 5.5 MEDIUM
Use-after-Free vulnerability in cflow 1.6 in the void call(char *name, int line) function at src/parser.c, which could cause a denial of service via the pointer variable caller->callee.
