In many cases, DNS remains a goldmine to detect potentially malicious activity. DNS can be used in multiple ways to bypass securitycontrols. DNS tunnelling is a common way to establish connections with remote systems. It is often based on TXT records used to deliver the encoded payload. TXT records are also used for good reasons, …

Drupal 8 before 8.2.8 and 8.3 before 8.3.1 allows critical access bypass by authenticated users if the RESTful Web Services (rest) module is enabled and the site allows PATCH requests.
An issue was discovered in Unitrends Enterprise Backup before 9.1.1. The function downloadFile in api/includes/restore.php blindly accepts any filename passed to /api/restore/download as valid. This allows an authenticated attacker to read any file in the filesystem that the web server has access to, aka Local File Inclusion (LFI).
An authenticated user of Unitrends Enterprise Backup before 9.1.2 can execute arbitrary OS commands by sending a specially crafted filename to the /api/restore/download-files endpoint, related to the downloadFiles function in api/includes/restore.php.
Samsung Android devices with L(5.0/5.1), M(6.0), and N(7.x) software allow attackers to obtain sensitive information by reading a world-readable log file after an unexpected reboot. The Samsung ID is SVE-2017-8290.
The cookie feature in the packet action API implementation in net/sched/act_api.c in the Linux kernel 4.11.x through 4.11-rc7 mishandles the tb nlattr array, which allows local users to cause a denial of service (uninitialized memory access and refcount underflow, and system hang or crash) or possibly have unspecified other impact via “tc filter add” commands …
Zyxel WRE6505 devices have a default TELNET password of 1234 for the root and admin accounts, which makes it easier for remote attackers to conduct DNS hijacking attacks by reconfiguring the built-in dnshijacker process.
Artifex jbig2dec 0.13, as used in Ghostscript, allows out-of-bounds writes because of an integer overflow in the jbig2_build_huffman_table function in jbig2_huffman.c during operations on a crafted JBIG2 file, leading to a denial of service (application crash) or possibly execution of arbitrary code.
Artifex jbig2dec 0.13 allows out-of-bounds writes and reads because of an integer overflow in the jbig2_image_compose function in jbig2_image.c during operations on a crafted .jb2 file, leading to a denial of service (application crash) or disclosure of sensitive information from process memory.
The aescrypt gem 1.0.0 for Ruby does not randomize the CBC IV for use with the AESCrypt.encrypt and AESCrypt.decrypt functions, which allows attackers to defeat cryptographic protection mechanisms via a chosen plaintext attack.
