User can overwrite arbitrary log files in support tar

In supportutils, before version 3.1-5.7.1 and if pacemaker is installed on the system, an unprivileged user could have overwritten arbitrary files in the directory that is used by supportutils to collect the log files.

Static temporary filename allows overwriting of files

Supportutils, before version 3.1-5.7.1, wrote data to static file /tmp/supp_log, allowing local attackers to overwrite files on systems without symlink protection

keepalived: Improper pathname validation allows for overwrite of arbitrary filenames via symlinks

keepalived 2.0.8 didn't check for pathnames with symlinks when writing data to a temporary file upon a call to PrintData or PrintStats. This allowed local users to overwrite arbitrary files if fs.protected_symlinks is set to 0, as demonstrated by a symlink from /tmp/keepalived.data or /tmp/keepalived.stats to /etc/passwd.

firefox: WebExtensions can load arbitrary URLs through pipe separators

Limitations on the URIs allowed to WebExtensions by the browser.windows.create API can be bypassed when a pipe in the URL field is used within the extension to load multiple pages as a single argument. This could allow a malicious WebExtension to open privileged about: or file: locations. This vulnerability affects Firefox < 64.

firefox: WebExtension content scripts can be loaded in about: pages

WebExtension content scripts can be loaded into about: pages in some circumstances, in violation of the permissions granted to extensions. This could allow an extension to interfere with the loading and usage of these pages and use capabilities that were intended to be restricted from extensions. This vulnerability affects Firefox < 64.

Static tempfile name allows overwriting of arbitrary files

In yast2-multipath before version 4.1.1 a static temporary filename allows local attackers to overwrite files on systems without symlink protection

Jekyll through 3.6.2, 3.7.x through 3.7.3, and 3.8.x through 3.8.3 allows attackers to access arbitrary files by specifying a symlink in the "include" key in the "_config.yml" file.

Due to incorrect access control, unauthenticated remote attackers can view the /video.mjpg video stream of certain ABUS TVIP cameras.

Denial of service via crafting malicious link and sending it to a privileged user can cause Denial of Service in Kraftway 24F2XG Router firmware version 3.5.30.1118.

Entes EMG12 versions 2.57 and prior an information exposure through query strings vulnerability in the web interface has been identified, which may allow an attacker to impersonate a legitimate user and execute arbitrary code.

glusterfs: glusterfs server exploitable via symlinks to relative paths

It was found that the fix for CVE-2018-10927, CVE-2018-10928, CVE-2018-10929, CVE-2018-10930, and CVE-2018-10926 was incomplete. A remote, authenticated attacker could use one of these flaws to execute arbitrary code, create arbitrary files, or cause denial of service on glusterfs server nodes via symlinks to relative paths.

smart_proxy_dynflow: Authentication bypass in Foreman remote execution feature

An authentication bypass flaw was found in the smart_proxy_dynflow component used by Foreman. A malicious attacker can use this flaw to remotely execute arbitrary commands on machines managed by vulnerable Foreman instances, in a highly privileged context.

h2: Information Exposure due to insecure handling of permissions in the backup

An issue was discovered in H2 1.4.197. Insecure handling of permissions in the backup function allows attackers to read sensitive files (outside of their permissions) via a symlink to a fake database file.

In HTSlib 1.8, a race condition in cram/cram_io.c might allow local users to overwrite arbitrary files via a symlink attack.

An issue was discovered in Cinnamon 1.9.2 through 3.8.6. The cinnamon-settings-users.py GUI runs as root and allows configuration of (for example) other users' icon files in _on_face_browse_menuitem_activated and _on_face_menuitem_activated. These icon files are written to the respective user's $HOME/.face location. If an unprivileged user prepares a symlink pointing to an arbitrary location, then this location will be overwritten with the icon content.

passenger: SpawningKit allows malicious applications to replace files and directories allowing for arbitrary reads and writes

During the spawning of a malicious Passenger-managed application, SpawningKit in Phusion Passenger 5.3.x before 5.3.2 allows such applications to replace key files or directories in the spawning communication directory with symlinks. This then could result in arbitrary reads and writes, which in turn can result in information disclosure and privilege escalation.

perl: Directory traversal in Archive::Tar

In Perl through 5.26.2, the Archive::Tar module allows remote attackers to bypass a directory-traversal protection mechanism, and overwrite arbitrary files, via an archive file containing a symlink and a regular file with the same name.

Information leakage vulnerability in the administrative console in Dialogic PowerMedia XMS through 3.5 allows remote attackers to read arbitrary files from the /var/ directory because a symlink exists under the web root.

libssh: Authentication Bypass due to improper message callbacks implementation

A vulnerability was found in libssh's server-side state machine before versions 0.7.6 and 0.8.4. A malicious client could create channels without first performing authentication, resulting in unauthorized access.

glusterfs: Improper resolution of symlinks allows for privilege escalation

A flaw was found in RPC request using gfs3_symlink_req in glusterfs server which allows symlink destinations to point to file paths outside of the gluster volume. An authenticated attacker could use this flaw to create arbitrary symlinks pointing anywhere on the server and execute arbitrary code on glusterfs server nodes.
