kubernetes: Malicious containers can delete any file from the node

In Kubernetes versions 1.3.x, 1.4.x, 1.5.x, 1.6.x and prior to versions 1.7.14, 1.8.9 and 1.9.4 containers using a secret, configMap, projected or downwardAPI volume can trigger deletion of arbitrary files/directories from the nodes where they are running.

kubernetes: Volume security can be sidestepped with innocent emptyDir and subpath

In Kubernetes versions 1.3.x, 1.4.x, 1.5.x, 1.6.x and prior to versions 1.7.14, 1.8.9 and 1.9.4 containers using subpath volume mounts with any volume type (including non-privileged pods, subject to file permissions) can access files/directories outside of the volume, including the host's filesystem.

Syncthing version 0.14.33 and older is vulnerable to symlink traversal resulting in arbitrary file overwrite

Qemu: 9p: virtfs allows guest to access host filesystem

Qemu before version 2.9 is vulnerable to an improper link following when built with the VirtFS. A privileged user inside guest could use this flaw to access host file system beyond the shared folder and potentially escalating their privileges on a host.

katello-debug: Possible symlink attacks due to use of predictable file names

A flaw was found in katello-debug before 3.4.0 where certain scripts and log files used insecure temporary files. A local user could exploit this flaw to conduct a symbolic-link attack, allowing them to overwrite the contents of arbitrary files.

nagios: Unsafe ownership change leading to privilege escalation

A privilege escalation vulnerability was found in nagios 4.2.x that occurs in daemon-init.in when creating necessary files and insecurely changing the ownership afterwards. It's possible for the local attacker to create symbolic links before the files are to be created and possibly escalating the privileges with the ownership change.

curl: Case insensitive password comparison

A flaw was found in curl before version 7.51.0 When re-using a connection, curl was doing case insensitive comparisons of user name and password with the existing connections. This means that if an unused connection with proper credentials exists for a protocol that has connection-scoped credentials, an attacker can cause that connection to be reused if s/he knows the case-insensitive version of the correct password.

The web server in Phoenix Contact ILC PLCs can be accessed without authenticating even if the authentication mechanism is enabled.

abrt: does not validate contents of uploaded problem reports

daemon/abrt-handle-upload.in in Automatic Bug Reporting Tool (ABRT), when moving problem reports from /var/spool/abrt-upload, allows local users to write to arbitrary files or possibly have other unspecified impact via a symlink attack on (1) /var/spool/abrt or (2) /var/tmp/abrt.

abrt: default event scripts follow symbolic links

The default event handling scripts in Automatic Bug Reporting Tool (ABRT) allow local users to gain privileges as demonstrated by a symlink attack on a var_log_messages file.

open build service source server symlink exploitation via source patch

In open buildservice 2.6 before 2.6.3, 2.5 before 2.5.7 and 2.4 before 2.4.8 the source service patch application could generate non-standard files like symlinks or device nodes, which could allow buildservice users to break of confinement or cause denial of service attacks on the source service.

clipedit in the Clipboard module for Perl allows local users to delete arbitrary files via a symlink attack on /tmp/clipedit$$.

Baxter SIGMA Spectrum Infusion System version 6.05 (model 35700BAX) with wireless battery module (WBM) version 16 is remotely accessible via Port 22/SSH without authentication. A remote attacker may be able to make unauthorized configuration changes to the WBM, as well as issue commands to access account credentials and shared keys. Baxter asserts that this vulnerability only allows access to features and functionality on the WBM and that the SIGMA Spectrum infusion pump cannot be controlled from the WBM. Baxter has released a new version of the SIGMA Spectrum Infusion System, Version 8, which incorporates hardware and software changes.

lib/vlad/dba/mysql.rb in the VladTheEnterprising gem 0.2 for Ruby allows local users to write to arbitrary files via a symlink attack on /tmp/my.cnf.#{target_host}.

The scheme48-send-definition function in cmuscheme48.el in Scheme 48 allows local users to write to arbitrary files via a symlink attack on /tmp/s48lose.tmp.

fish before 2.1.1 allows local users to write to arbitrary files via a symlink attack on (1) /tmp/fishd.log.%s, (2) /tmp/.pac-cache.$USER, (3) /tmp/.yum-cache.$USER, or (4) /tmp/.rpm-cache.$USER.

The main function in android_main.cpp in thermald allows local users to write to arbitrary files via a symlink attack on /tmp/thermald.pid.

python-rply before 0.7.4 insecurely creates temporary files.

numpy: f2py insecure temporary file use

(1) core/tests/test_memmap.py, (2) core/tests/test_multiarray.py, (3) f2py/f2py2e.py, and (4) lib/tests/test_io.py in NumPy before 1.8.1 allow local users to write to arbitrary files via a symlink attack on a temporary file.

Insecure temp file usage in Ubuntu UI toolkit

On desktop, Ubuntu UI Toolkit's StateSaver would serialise data on tmp/ files which an attacker could use to expose potentially sensitive data. StateSaver would also open files without the O_EXCL flag. An attacker could exploit this to launch a symlink attack, though this is partially mitigated by symlink and hardlink restrictions in Ubuntu. Fixed in 1.1.1188+14.10.20140813.4-0ubuntu1.
