CVE-2021-39522 1 Gnu 1 Libredwg 2026-06-17 6.8 MEDIUM 8.8 HIGH
An issue was discovered in libredwg through v0.10.1.3751. bit_wcs2len() in bits.c has a heap-based buffer overflow.
CVE-2021-39521 1 Gnu 1 Libredwg 2026-06-17 4.3 MEDIUM 6.5 MEDIUM
An issue was discovered in libredwg through v0.10.1.3751. A NULL pointer dereference exists in the function bit_read_BB() located in bits.c. It allows an attacker to cause Denial of Service.
CVE-2021-38185 1 Gnu 1 Cpio 2026-06-17 6.8 MEDIUM 7.8 HIGH
GNU cpio through 2.13 allows attackers to execute arbitrary code via a crafted pattern file, because of a dstring.c ds_fgetstr integer overflow that triggers an out-of-bounds heap write. NOTE: it is unclear whether there are common cases where the pattern file, associated with the -E option, is untrusted data.
CVE-2021-37322 1 Gnu 2 Binutils, Gcc 2026-06-17 6.8 MEDIUM 7.8 HIGH
GCC c++filt v2.26 was discovered to contain a use-after-free vulnerability via the component cplus-dem.c.
CVE-2021-36080 1 Gnu 1 Libredwg 2026-06-17 6.8 MEDIUM 8.8 HIGH
GNU LibreDWG 0.12.3.4163 through 0.12.3.4191 has a double-free in bit_chain_free (called from dwg_encode_MTEXT and dwg_encode_add_object).
CVE-2021-34337 1 Gnu 1 Mailman 2026-06-17 N/A 6.3 MEDIUM
An issue was discovered in Mailman Core before 3.3.5. An attacker with access to the REST API could use timing attacks to determine the value of the configured REST API password and then make arbitrary REST API calls. The REST API is bound to localhost by default, limiting the ability for attackers to exploit this, but can optionally be made to listen on other interfaces.
CVE-2021-32256 1 Gnu 1 Binutils 2026-06-17 N/A 6.5 MEDIUM
An issue was discovered in GNU libiberty, as distributed in GNU Binutils 2.36. It is a stack-overflow issue in demangle_type in rust-demangle.c.
CVE-2021-30184 2 Fedoraproject, Gnu 2 Fedora, Chess 2026-06-17 6.8 MEDIUM 7.8 HIGH
GNU Chess 6.2.7 allows attackers to execute arbitrary code via crafted PGN (Portable Game Notation) data. This is related to a buffer overflow in the use of a .tmp.epd temporary file in the cmd_pgnload and cmd_pgnreplay functions in frontend/cmd.cc.
CVE-2021-28968 1 Gnu 1 Punbb 2026-06-17 3.5 LOW 5.4 MEDIUM
An issue was discovered in PunBB before 1.4.6. An XSS vulnerability in the [email] BBcode tag allows (with authentication) injecting arbitrary JavaScript into any forum message.
CVE-2021-28237 1 Gnu 1 Libredwg 2026-06-17 7.5 HIGH 9.8 CRITICAL
LibreDWG v0.12.3 was discovered to contain a heap-buffer overflow via decode_preR13.
CVE-2021-28236 1 Gnu 1 Libredwg 2026-06-17 5.0 MEDIUM 7.5 HIGH
LibreDWG v0.12.3 was discovered to contain a NULL pointer dereference via out_dxfb.c.
CVE-2021-27851 1 Gnu 1 Guix 2026-06-17 2.1 LOW 5.5 MEDIUM
A security vulnerability that can lead to local privilege escalation has been found in ’guix-daemon’. It affects multi-user setups in which ’guix-daemon’ runs locally. The attack consists in having an unprivileged user spawn a build process, for instance with `guix build`, that makes its build directory world-writable. The user then creates a hardlink to a root-owned file such as /etc/shadow in that build directory. If the user passed the --keep-failed option and the build eventually fails, the daemon changes ownership of the whole build tree, including the hardlink, to the user. At that point, the user has write access to the target file. Versions after and including v0.11.0-3298-g2608e40988, and versions prior to v1.2.0-75109-g94f0312546 are vulnerable.
CVE-2021-26937 3 Debian, Fedoraproject, Gnu 3 Debian Linux, Fedora, Screen 2026-06-17 7.5 HIGH 9.8 CRITICAL
encoding.c in GNU Screen through 4.8.0 allows remote attackers to cause a denial of service (invalid write access and application crash) or possibly have unspecified other impact via a crafted UTF-8 character sequence.
CVE-2021-20294 1 Gnu 1 Binutils 2026-06-17 6.8 MEDIUM 7.8 HIGH
A flaw was found in binutils readelf 2.35 program. An attacker who is able to convince a victim using readelf to read a crafted file could trigger a stack buffer overflow, out-of-bounds write of arbitrary data supplied by the attacker. The highest impact of this flaw is to confidentiality, integrity, and availability.
CVE-2021-20284 2 Gnu, Netapp 3 Binutils, Cloud Backup, Ontap Select Deploy Administration Utility 2026-06-17 4.3 MEDIUM 5.5 MEDIUM
A flaw was found in GNU Binutils 2.35.1, where there is a heap-based buffer overflow in _bfd_elf_slurp_secondary_reloc_section in elf.c due to the number of symbols not calculated correctly. The highest threat from this vulnerability is to system availability.
CVE-2021-20233 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. Setparam_prefix() in the menu rendering code performs a length calculation on the assumption that expressing a quoted single quote will require 3 characters, while it actually requires 4 characters which allows an attacker to corrupt memory by one byte for each quote in the input. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
