deepin-clone before 1.1.3 uses a predictable path /tmp/.deepin-clone/mount/<block-dev-basename> in the Helper::temporaryMountDevice() function to temporarily mount a file system as root. An unprivileged user can prepare a symlink at this location to have the file system mounted in an arbitrary location. By winning a race condition, the attacker can also enter the mount point, thereby preventing a subsequent unmount of the file system.

The open_log function in log.c in Exim 4.72 and earlier does not check the return value from (1) setuid or (2) setgid system calls, which allows local users to append log data to arbitrary files via a symlink attack.

writtercontrol in cdcontrol 1.90 allows local users to overwrite arbitrary files via a symlink attack on /tmp/v-recorder*-out temporary files.

GNOME Display Manager (gdm) 2.x before 2.32.1 allows local users to change the ownership of arbitrary files via a symlink attack on a (1) dmrc or (2) face icon file under /var/cache/gdm/.

fwb_install in fwbuilder 2.1.19 allows local users to overwrite arbitrary files via a symlink attack on a /tmp/ssh-agent.##### temporary file.

By exploiting a time of check to time of use (TOCTOU) race condition during the Endpoint Security for Linux Threat Prevention and Firewall (ENSL TP/FW) installation process, a local user can perform a privilege escalation attack to obtain administrator privileges for the purpose of executing arbitrary code through insecure use of predictable temporary file locations.

nvidia-cg-toolkit-installer in nvidia-cg-toolkit 2.0.0015 allows local users to overwrite arbitrary files via a symlink attack on the /tmp/nvidia-cg-toolkit-manifest temporary file.

tkusr in tkusr 0.82 allows local users to overwrite arbitrary files via a symlink attack on the /tmp/tkusr.pgm temporary file.

emacs-jabber in emacs-jabber 0.7.91 allows local users to overwrite arbitrary files via a symlink attack on a /tmp/*.log temporary file.

dtc 0.29.6 allows local users to overwrite arbitrary files via a symlink attack on (a) /tmp/awstats.log, (b) /tmp/spam.log.#####, and (c) /tmp/spam_err.log temporary files, related to the (1) accesslog.php and (2) sa-wrapper scripts.

The (1) rccs and (2) STUFF scripts in lmbench 3.0-a7 allow local users to overwrite arbitrary files via a symlink attack on a /tmp/sdiff.##### temporary file.

mafft-homologs in mafft 6.240 allows local users to overwrite arbitrary files via a symlink attack on (1) /tmp/_vf#?????, (2) /tmp/_if#?????, (3) /tmp/_pf#?????, (4) /tmp/_af#?????, (5) /tmp/_rid#?????, (6) /tmp/_res#?????, (7) /tmp/_q#?????, and (8) /tmp/_bf#????? temporary files.

aegis 4.24 and aegis-web 4.24 allow local users to overwrite arbitrary files via a symlink attack on (a) /tmp/#####, (b) /tmp/#####.intro, (c) /tmp/aegis.#####.ae, (d) /tmp/aegis.#####, (e) /tmp/aegis.#####.1, (f) /tmp/aegis.#####.2, (g) /tmp/aegis.#####.log, and (h) /tmp/aegis.#####.out temporary files, related to the (1) bng_dvlpd.sh, (2) bng_rvwd.sh, (3) awt_dvlp.sh, (4) awt_intgrtn.sh, and (5) aegis.cgi scripts.

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.

asr in Oracle Auto Service Request in Oracle Support Tools before 4.3.2 allows local users to modify arbitrary files via a symlink attack on a predictable filename in /tmp.

A local attacker can create a hard-link between a file to which the Check Point Endpoint Security client for Windows before E80.96 writes and another BAT file, then by impersonating the WPAD server, the attacker can write BAT commands into that file that will later be run by the user or the system.
