Improper Link Resolution Before File Access ('Link Following')

base/logging.c in Nagios Core before 4.2.4 allows local users with access to an account in the nagios group to gain root privileges via a symlink attack on the log file. NOTE: this can be leveraged by remote attackers using CVE-2016-9565.Show less

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.Show less

The nginx package before 1.6.2-5+deb8u3 on Debian jessie, the nginx packages before 1.4.6-1ubuntu3.6 on Ubuntu 14.04 LTS, before 1.10.0-0ubuntu0.16.04.3 on Ubuntu 16.04 LTS, and before 1.10.1-0ubuntu1.1 on Ubuntu 16.10, and the nginx ebuild before 1.10.2-r3 on Gentoo allow local users with access to the web server user account to gain root privileges via a symlink attack on the error log.Show less

The installation script studioexpressinstall for Teradata Studio Express 15.12.00.00 creates files in /tmp insecurely. A malicious local user could create a symlink in /tmp and possibly clobber system files or perhaps elevate privileges.Show less

The create_script function in the lxc_container module in Ansible before 1.9.6-1 and 2.x before 2.0.2.0 allows local users to write to arbitrary files or gain privileges via a symlink attack on (1) /opt/.lxc-attach-script, (2) the archived container in the archive_path directory, or the (3) lxc-attach-script.log or (4) lxc-attach-script.err files in the temporary directory.Show less

Gummi 0.6.5 allows local users to write to arbitrary files via a symlink attack on a temporary dot file that uses the name of an existing file and a (1) .aux, (2) .log, (3) .out, (4) .pdf, or (5) .toc extension for the file name, as demonstrated by .thesis.tex.aux.Show less

The abrt-hook-ccpp help program in Automatic Bug Reporting Tool (ABRT) before 2.7.1 allows local users with certain permissions to gain privileges via a symlink attack on a file with a predictable name, as demonstrated by /var/tmp/abrt/abrt-hax-coredump or /var/spool/abrt/abrt-hax-coredump.Show less

The abrt-action-install-debuginfo-to-abrt-cache help program in Automatic Bug Reporting Tool (ABRT) before 2.7.1 allows local users to write to arbitrary files via a symlink attack on unpacked.cpio in a pre-created directory with a predictable name in /var/tmp.Show less

vzctl before 4.9.4 determines the virtual environment (VE) layout based on the presence of root.hdd/DiskDescriptor.xml in the VE private directory, which allows local simfs container (CT) root users to change the root password for arbitrary ploop containers, as demonstrated by a symlink attack on the ploop container root.hdd file and then access a control panel.Show less
