CVE-2026-56392 1 Gnu 1 Coreutils 2026-07-24 N/A
GNU coreutils unexpand is vulnerable to a heap-based buffer overflow due to an integer overflow during buffer allocation when processing large tab stop (-t) values. The multiplication used to calculate the allocation size can wrap around, resulting in an undersized buffer. When processing crafted input, subsequent writes exceed the allocated memory, leading to an out‑of‑bounds heap write. When running GNU coreutils unexpand with attacker-provided large tab stop (-t) arguments, this behavior leads to a crash and potentially achieve a heap write primitive depending on memory layout. This issue has been fixed in the commit b60a159fdc5bfcf9988d3a4cb6f53abe8ad5d35d
CVE-2026-56391 1 Gnu 1 Coreutils 2026-07-24 N/A
GNU coreutils uniq is vulnerable to an out‑of‑bounds read due to incorrect handling of multibyte input when the -w (--check-chars) option is used. The find_field() function miscalculates the byte length of characters by repeatedly processing a fixed pointer instead of advancing through the input, resulting in an inflated length value. This incorrect length is later used in a memcmp operation, causing reads beyond the allocated buffer when processing crafted multibyte input. When running GNU coreutils uniq with attacker-provided arguments, this behavior leads to a crash and potential adjacent heap memory exposure. This issue has been fixed in the commit d64e35a8a4c0e4608321433e0d84d917e4e36371.
CVE-2009-4135 3 Canonical, Fedoraproject, Gnu 3 Ubuntu Linux, Fedora, Coreutils 2026-04-23 N/A
The distcheck rule in dist-check.mk in GNU coreutils 5.2.1 through 8.1 allows local users to gain privileges via a symlink attack on a file in a directory tree under /tmp.
CVE-2008-1946 2 Gnu, Redhat 2 Coreutils, Enterprise Linux 2026-04-23 N/A
The default configuration of su in /etc/pam.d/su in GNU coreutils 5.2.1 allows local users to gain the privileges of a (1) locked or (2) expired account by entering the account name on the command line, related to improper use of the pam_succeed_if.so module.
CVE-2005-1039 1 Gnu 1 Coreutils 2026-04-16 N/A
Race condition in Core Utilities (coreutils) 5.2.1, when (1) mkdir, (2) mknod, or (3) mkfifo is running with the -m switch, allows local users to modify permissions of other files.
CVE-2024-0684 1 Gnu 1 Coreutils 2025-11-04 5.5 Medium
A flaw was found in the GNU coreutils "split" program. A heap overflow with user-controlled data of multiple hundred bytes in length could occur in the line_bytes_split() function, potentially leading to an application crash and denial of service.
CVE-2015-1865 1 Gnu 1 Coreutils 2025-08-06 5.1 Medium
fts.c in coreutils 8.4 allows local users to delete arbitrary files.
CVE-2017-18018 1 Gnu 1 Coreutils 2025-06-09 7.1 High
In GNU Coreutils through 8.29, chown-core.c in chown and chgrp does not prevent replacement of a plain file with a symlink during use of the POSIX "-R -L" options, which allows local users to modify the ownership of arbitrary files by leveraging a race condition.
CVE-2016-2781 1 Gnu 1 Coreutils 2025-06-09 4.6 Medium
chroot in GNU coreutils, when used with --userspec, allows local users to escape to the parent session via a crafted TIOCSTI ioctl call, which pushes characters to the terminal's input buffer.
CVE-2014-9471 2 Canonical, Gnu 2 Ubuntu Linux, Coreutils 2025-04-12 N/A
The parse_datetime function in GNU coreutils allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted date string, as demonstrated by the "--date=TZ="123"345" @1" string to the touch or date command.
CVE-2015-4042 1 Gnu 1 Coreutils 2024-11-21 9.8 Critical
Integer overflow in the keycompare_mb function in sort.c in sort in GNU Coreutils through 8.23 might allow attackers to cause a denial of service (application crash) or possibly have unspecified other impact via long strings.
CVE-2015-4041 1 Gnu 1 Coreutils 2024-11-21 7.8 High
The keycompare_mb function in sort.c in sort in GNU Coreutils through 8.23 on 64-bit platforms performs a size calculation without considering the number of bytes occupied by multibyte characters, which allows attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via long UTF-8 strings.
