| CVE-2021-20197 | 4 Broadcom, Gnu, Netapp and 1 more | 6 Brocade Fabric Operating System Firmware, Binutils, Cloud Backup and 3 more | 2023-02-12 | 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-2021-35939 | 2 Redhat, Rpm | 2 Enterprise Linux, Rpm | 2023-02-04 | N/A | 6.7 MEDIUM |
| It was found that the fix for CVE-2017-7500 and CVE-2017-7501 was incomplete: the check was only implemented for the parent directory of the file to be created. A local unprivileged user who owns another ancestor directory could potentially use this flaw to gain root privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2022-26659 | 2 Docker, Microsoft | 2 Docker Desktop, Windows | 2023-02-01 | 3.6 LOW | 7.1 HIGH |
| Docker Desktop installer on Windows in versions before 4.6.0 allows an attacker to overwrite any administrator writable files by creating a symlink in place of where the installer writes its log file. Starting from version 4.6.0, the Docker Desktop installer, when run elevated, will write its log files to a location not writable by non-administrator users. | |||||
| CVE-2019-3691 | 2 Opensuse, Suse | 3 Factory, Munge, Suse Linux Enterprise Server | 2023-01-31 | 7.2 HIGH | 7.8 HIGH |
| A Symbolic Link (Symlink) Following vulnerability in the packaging of munge in SUSE Linux Enterprise Server 15; openSUSE Factory allowed local attackers to escalate privileges from user munge to root. This issue affects: SUSE Linux Enterprise Server 15 munge versions prior to 0.5.13-4.3.1. openSUSE Factory munge versions prior to 0.5.13-6.1. | |||||
| CVE-2020-6012 | 1 Checkpoint | 1 Zonealarm Anti-ransomware | 2023-01-31 | 4.4 MEDIUM | 7.4 HIGH |
| ZoneAlarm Anti-Ransomware before version 1.0.713 copies files for the report from a directory with low privileges. A sophisticated timed attacker can replace those files with malicious or linked content, such as exploiting CVE-2020-0896 on unpatched systems or using symbolic links. This allows an unprivileged user to enable escalation of privilege via local access. | |||||
| CVE-2020-7040 | 4 Canonical, Debian, Opensuse and 1 more | 5 Ubuntu Linux, Debian Linux, Backports Sle and 2 more | 2023-01-27 | 9.3 HIGH | 8.1 HIGH |
| storeBackup.pl in storeBackup through 3.5 relies on the /tmp/storeBackup.lock pathname, which allows symlink attacks that possibly lead to privilege escalation. (Local users can also create a plain file named /tmp/storeBackup.lock to block use of storeBackup until an admin manually deletes that file.) | |||||
| CVE-2016-6664 | 3 Mariadb, Oracle, Percona | 4 Mariadb, Mysql, Percona Server and 1 more | 2023-01-24 | 6.9 MEDIUM | 7.0 HIGH |
| mysqld_safe in Oracle MySQL through 5.5.51, 5.6.x through 5.6.32, and 5.7.x through 5.7.14; MariaDB; Percona Server before 5.5.51-38.2, 5.6.x before 5.6.32-78-1, and 5.7.x before 5.7.14-8; and Percona XtraDB Cluster before 5.5.41-37.0, 5.6.x before 5.6.32-25.17, and 5.7.x before 5.7.14-26.17, when using file-based logging, allows local users with access to the mysql account to gain root privileges via a symlink attack on error logs and possibly other files. | |||||
| CVE-2021-37701 | 4 Debian, Npmjs, Oracle and 1 more | 4 Debian Linux, Tar, Graalvm and 1 more | 2023-01-19 | 4.4 MEDIUM | 8.6 HIGH |
| The npm package "tar" (aka node-tar) before versions 4.4.16, 5.0.8, and 6.1.7 has an arbitrary file creation/overwrite and arbitrary code execution vulnerability. node-tar aims to guarantee that any file whose location would be modified by a symbolic link is not extracted. This is, in part, achieved by ensuring that extracted directories are not symlinks. Additionally, in order to prevent unnecessary stat calls to determine whether a given path is a directory, paths are cached when directories are created. This logic was insufficient when extracting tar files that contained both a directory and a symlink with the same name as the directory, where the symlink and directory names in the archive entry used backslashes as a path separator on posix systems. The cache checking logic used both `\` and `/` characters as path separators, however `\` is a valid filename character on posix systems. By first creating a directory, and then replacing that directory with a symlink, it was thus possible to bypass node-tar symlink checks on directories, essentially allowing an untrusted tar file to symlink into an arbitrary location and subsequently extracting arbitrary files into that location, thus allowing arbitrary file creation and overwrite. Additionally, a similar confusion could arise on case-insensitive filesystems. If a tar archive contained a directory at `FOO`, followed by a symbolic link named `foo`, then on case-insensitive file systems, the creation of the symbolic link would remove the directory from the filesystem, but _not_ from the internal directory cache, as it would not be treated as a cache hit. A subsequent file entry within the `FOO` directory would then be placed in the target of the symbolic link, thinking that the directory had already been created. These issues were addressed in releases 4.4.16, 5.0.8 and 6.1.7. The v3 branch of node-tar has been deprecated and did not receive patches for these issues. If you are still using a v3 release we recommend you update to a more recent version of node-tar. If this is not possible, a workaround is available in the referenced GHSA-9r2w-394v-53qc. | |||||
| CVE-2018-6557 | 2 Base-files Project, Canonical | 2 Base-files, Ubuntu Linux | 2023-01-18 | 4.4 MEDIUM | 7.0 HIGH |
| The MOTD update script in the base-files package in Ubuntu 18.04 LTS before 10.1ubuntu2.2, and Ubuntu 18.10 before 10.1ubuntu6 incorrectly handled temporary files. A local attacker could use this issue to cause a denial of service, or possibly escalate privileges if kernel symlink restrictions were disabled. | |||||
