Lynis is an auditing tool for Unix (specialists). It scans the system and available software to detect security issues. Beside security related information it will also scan for general system information, installed packages and configuration mistakes. This software aims in assisting automated auditing, software patch management, vulnerability and malware scanning of Unix based systems.
1358a0de753ab5359e04ec7e53b62294d1a11ffe2be493dddb0d143881681290Stegano is a basic Python Steganography module. Stegano implements two methods of hiding: using the red portion of a pixel to hide ASCII messages, and using the Least Significant Bit (LSB) technique. It is possible to use a more advanced LSB method based on integers sets. The sets (Sieve of Eratosthenes, Fermat, Carmichael numbers, etc.) are used to select the pixels used to hide the information.

ee725f310771fc35d7cc3ac15e95e4674c6a5a8b5ec3ed497c4f369a51d9cb9eFreeBSD Security Advisory - If an SSL/TLS server or client is running on a 32-bit host, and a specific cipher is being used, then a truncated packet can cause that server or client to perform an out-of-bounds read, usually resulting in a crash. There is a carry propagating bug in the x86_64 Montgomery squaring procedure. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be very significant and likely only accessible to a limited number of attackers. An attacker would additionally need online access to an unpatched system using the target private key in a scenario with persistent DH parameters and a private key that is shared between multiple clients. Various other issues have also been identified.

d4c6af8f0e3dd4d9e278a3515440e0936dca73862bdc065cf6bd5e2d14200203Red Hat Security Advisory 2017-0300-01 - The OpenStack Oslo Middleware library provides components that can be injected into WSGI pipelines to intercept request and response flows. The base class can be enhanced with functionality like adding or updating HTTP headers, or to offer support for limiting size or connections. Security Fix: An information-disclosure flaw was found in oslo.middleware. Software using the CatchError class could include sensitive values in a traceback's error message. Remote users could exploit this flaw to obtain sensitive information from OpenStack component error logs.
c3359bf03135b1a5ff63d07bd5d660438d80e7a084cdb79b79c57de44ee006f0Ubuntu Security Notice 3142-2 - USN-3142-1 fixed vulnerabilities in ImageMagick. The security fixes introduced a regression with text labels and a regression with the text coder. This update fixes the problem. It was discovered that ImageMagick incorrectly handled certain malformed image files. If a user or automated system using ImageMagick were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program. Various other issues were also addressed.

Security Fix: A use-after-free flaw was found in the way the Linux kernel's Datagram Congestion Control Protocol implementation freed SKB resources for a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option is set on the socket. A local, unprivileged user could use this flaw to alter the kernel memory, allowing them to escalate their privileges on the system.
