Util-linux Security Vulnerabilities

CVE-2020-21583

An issue was discovered in hwclock.13-v2.27 allows attackers to gain escalated privlidges or execute arbitrary commands via the path parameter when setting the...

CVE-2021-3995

A logic error was found in the libmount library of util-linux in the function that allows an unprivileged user to unmount a FUSE filesystem. This flaw allows an unprivileged local attacker to unmount FUSE filesystems that belong to certain other users who have a UID that is a prefix of the UID of.....

CVE-2021-3996

A logic error was found in the libmount library of util-linux in the function that allows an unprivileged user to unmount a FUSE filesystem. This flaw allows a local user on a vulnerable system to unmount other users' filesystems that are either world-writable themselves (like /tmp) or mounted in.....

CVE-2022-0563

A flaw was found in the util-linux chfn and chsh utilities when compiled with Readline support. The Readline library uses an "INPUTRC" environment variable to get a path to the library config file. When the library cannot parse the specified file, it prints an error message containing data from...

CVE-2021-37600

An integer overflow in util-linux through 2.37.1 can potentially cause a buffer overflow if an attacker were able to use system resources in a way that leads to a large number in the /proc/sysvipc/sem file. NOTE: this is unexploitable in GNU C Library environments, and possibly in all realistic...

CVE-2017-2616

A race condition was found in util-linux before 2.32.1 in the way su handled the management of child processes. A local authenticated attacker could use this flaw to kill other processes with root privileges under specific...

CVE-2018-7738

In util-linux before 2.32-rc1, bash-completion/umount allows local users to gain privileges by embedding shell commands in a mountpoint name, which is mishandled during a umount command (within Bash) by a different user, as demonstrated by logging in as root and entering umount followed by a tab...

CVE-2015-5224

The mkostemp function in login-utils in util-linux when used incorrectly allows remote attackers to cause file name collision and possibly other...

CVE-2016-5011

The parse_dos_extended function in partitions/dos.c in the libblkid library in util-linux allows physically proximate attackers to cause a denial of service (memory consumption) via a crafted MSDOS partition table with an extended partition boot record at zero...

CVE-2014-9114

Blkid in util-linux before 2.26rc-1 allows local users to execute arbitrary...

CVE-2016-2779

runuser in util-linux allows local users to escape to the parent session via a crafted TIOCSTI ioctl call, which pushes characters to the terminal's input...

CVE-2015-5218

Buffer overflow in text-utils/colcrt.c in colcrt in util-linux before 2.27 allows local users to cause a denial of service (crash) via a crafted file, related to the page global...

CVE-2013-0157

(a) mount and (b) umount in util-linux 2.14.1, 2.17.2, and probably other versions allow local users to determine the existence of restricted directories by (1) using the --guess-fstype command-line option or (2) attempting to mount a non-existent device, which generates different error messages...

CVE-2011-1675

mount in util-linux 2.19 and earlier attempts to append to the /etc/mtab.tmp file without first checking whether resource limits would interfere, which allows local users to trigger corruption of the /etc/mtab file via a process with a small RLIMIT_FSIZE value, a related issue to...

CVE-2011-1676

mount in util-linux 2.19 and earlier does not remove the /etc/mtab.tmp file after a failed attempt to add a mount entry, which allows local users to trigger corruption of the /etc/mtab file via multiple...

CVE-2011-1677

mount in util-linux 2.19 and earlier does not remove the /etc/mtab~ lock file after a failed attempt to add a mount entry, which has unspecified impact and local attack...

CVE-2008-1926

Argument injection vulnerability in login (login-utils/login.c) in util-linux-ng 2.14 and earlier makes it easier for remote attackers to hide activities by modifying portions of log events, as demonstrated by appending an "addr=" statement to the login name, aka "audit log...

CVE-2007-5191

mount and umount in util-linux and loop-aes-utils call the setuid and setgid functions in the wrong order and do not check the return values, which might allow attackers to gain privileges via helpers such as...

CVE-2006-7108

login in util-linux-2.12a skips pam_acct_mgmt and chauth_tok when authentication is skipped, such as when a Kerberos krlogin session has been established, which might allow users to bypass intended access policies that would be enforced by pam_acct_mgmt and...

CVE-2005-2876

umount in util-linux 2.8 to 2.12q, 2.13-pre1, and 2.13-pre2, and other packages such as loop-aes-utils, allows local users with unmount permissions to gain privileges via the -r (remount) option, which causes the file system to be remounted with just the read-only flag, which effectively clears...

CVE-2004-0080

The login program in util-linux 2.11 and earlier uses a pointer after it has been freed and reallocated, which could cause login to leak sensitive...

CVE-2003-0094

A patch for mcookie in the util-linux package for Mandrake Linux 8.2 and 9.0 uses /dev/urandom instead of /dev/random, which causes mcookie to use an entropy source that is more predictable than expected, which may make it easier for certain types of attacks to...

CVE-2001-1175

vipw in the util-linux package before 2.10 causes /etc/shadow to be world-readable in some cases, which would make it easier for local users to perform brute force password...

CVE-2001-1494

script command in the util-linux package before 2.11n allows local users to overwrite arbitrary files by setting a hardlink from the typescript log file to any file on the system, then having root execute the script...

CVE-2001-1147

The PAM implementation in /bin/login of the util-linux package before 2.11 causes a password entry to be rewritten across multiple PAM calls, which could provide the credentials of one user to a different user, when used in certain PAM modules such as...
