SUSE 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 the...

SUSE CVE-2006-7108

login in util-linux-2.12a skips pamacctmgmt and chauthtok 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 pamacctmgmt and chauthtok...

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 vectors...

SUSE 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 RLIMITFSIZE value, a related issue to CVE-2011-1089...

SUSE CVE-2016-5011

The parsedosextended 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 offset...

SUSE 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 conditions...

SUSE 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...

SUSE 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 a...

SUSE 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...

SUSE 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 t...
