Stegano 0.11.1
Posted Nov 22, 2022
Authored by Cedric Bonhomme | Site github.com

Stegano 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.

Changes: Fixed a bug in the command line when no sub-command is specified.

GNU Privacy Guard 2.3.8
Posted Oct 17, 2022
Site gnupg.org

GnuPG (the GNU Privacy Guard or GPG) is GNU's tool for secure communication and data storage. It can be used to encrypt data and to create digital signatures. It includes an advanced key management facility and is compliant with the proposed OpenPGP Internet standard as described in RFC2440. As such, it is meant to be compatible with PGP from NAI, Inc. Because it does not use any patented algorithms, it can be used without any restrictions.

Changes: Some new options and quite a few bug fixes in the changelog. New gpg-auth tool for authentication.

cryptmount Filesystem Manager 6.1.0
Posted Oct 10, 2022
Authored by RW Penney | Site cryptmount.sourceforge.net

cryptmount is a utility for creating and managing secure filing systems on GNU/Linux systems. After initial setup, it allows any user to mount or unmount filesystems on demand, solely by providing the decryption password, with any system devices needed to access the filing system being configured automatically. A wide variety of encryption schemes (provided by the kernel dm-crypt system and the libgcrypt library) can be used to protect both the filesystem and the access key. The protected filing systems can reside in either ordinary files or disk partitions. The package also supports encrypted swap partitions, and automatic configuration on system boot-up.

Changes: Improved udev settling schedule and filesystem syncs. Added partial support for compiling against libgcrypt-1.7. Improved waiting schedule for inter-process status locks. Improved stability of tests against legacy cryptsetup. Revised installation instructions and top-level README.

OpenSSH 9.1p1
Posted Oct 4, 2022
Authored by Damien Miller | Site openssh.com

This is a Linux/portable port of OpenBSD's excellent OpenSSH. OpenSSH is based on the last free version of Tatu Ylonen's SSH with all patent-encumbered algorithms removed, all known security bugs fixed, new features reintroduced, and many other clean-ups.

Changes: This release is focused on bug fixing. This release contains fixes for three minor memory safety problems. The portable OpenSSH project now signs commits and release tags using git's recent SSH signature support. 8 new features noted.

OpenStego Free Steganography Solution 0.8.5
Posted Sep 26, 2022
Authored by Samir Vaidya | Site github.com

OpenStego is a tool implemented in Java for generic steganography, with support for password-based encryption of the data. It supports plugins for various steganographic algorithms (currently, only Least Significant Bit algorithm is supported for images).

Changes: Handle file size not enough in case of embed watermark operation. Handle case where some files fail processing during wildcard operations. Handle JPEGs where APP0 marker is not the first in JFIF metadata. JDK fails reading such files even if image body is fine.

OpenSSL Toolkit 3.0.5
Posted Jul 5, 2022

OpenSSL is a robust, fully featured Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols with full-strength cryptography world-wide. The 3.x series is the current major version of OpenSSL.

Changes: The OpenSSL 3.0.4 release introduced a serious bug in the RSA implementation for X86_64 CPUs supporting the AVX512IFMA instructions. This issue makes the RSA implementation with 2048 bit private keys incorrect on such machines and memory corruption will happen during the computation. As a consequence of the memory corruption an attacker may be able to trigger a remote code execution on the machine performing the computation. SSL/TLS servers or other servers using 2048 bit RSA private keys running on machines supporting AVX512IFMA instructions of the X86_64 architecture are affected by this issue. An AES OCB mode issue was also addressed.

Changes: Fixed a bug in the BN_mod_sqrt() function that can cause it to loop forever for non-prime moduli. Added ciphersuites based on DHE_PSK (RFC 4279) and ECDHE_PSK (RFC 5489) to the list of ciphersuites providing Perfect Forward Secrecy as required by SECLEVEL greater than or equal to 3. Made the AES constant time code for no-asm configurations optional due to the resulting 95% performance degradation. Fixed PEM_write_bio_PKCS8PrivateKey() to make it possible to use empty passphrase strings. The negative return value handling of the certificate verification callback was reverted. The replacement is to set the verification retry state with the SSL_set_retry_verify() function.
