Warpinator through 1.2.14 allows access outside of an intended directory, as demonstrated by symbolic directory links.

Linux Mint Xreader EPUB File Parsing Directory Traversal Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Linux Mint Xreader. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the parsing of EPUB files. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-21897.

Linux Mint Xreader CBT File Parsing Argument Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Linux Mint Xreader. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the parsing of CBT files. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-22132.

Warpinator before 1.6.0 allows remote file deletion via directory traversal in topdirbasenames.

Clemens Fries reported that, when using Cinnamon, it was possible to bypass the screensaver lock:

An attacker with physical access to the machine could use this flaw to take over the locked desktop session.

A patch is currently not yet available.

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 onfacebrowsemenuitemactivated and onfacemenuitemactivated. 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.

A heap-based buffer overflow in cairoimagesurfacecreatefromjpeg() in extensions/cairoio/cairo-image-surface-jpeg.c in GNOME gThumb before 3.8.3 and Linux Mint Pix before 2.4.5 allows attackers to cause a crash and potentially execute arbitrary code via a crafted JPEG file.

mintinstall (aka Software Manager) 7.9.9 for Linux Mint allows code execution if a REVIEWSCACHE file is controlled by an attacker, because an unpickle occurs. This is resolved in 8.0.0 and backports.
