Google Discloses Severe Bug in Libgcrypt Encryption Library—Impacting Many Projects

January 31, 2021Ravie Lakshmanan
A "severe" vulnerability in GNU Privacy Guard (GnuPG)'s Libgcrypt encryption software could have allowed an attacker to write arbitrary data to the target machine, potentially leading to remote code execution. The flaw, which affects version 1.9.0 of libgcrypt, was discovered on January 28 by Tavis Ormandy of Project Zero, a security research unit within Google dedicated to finding zero-day bugs in hardware and software systems. No other versions of Libgcrypt are affected by the vulnerability. "There is a  heap buffer overflow  in libgcrypt due to an incorrect assumption in the block buffer management code," Ormandy  said . "Just decrypting some data can overflow a heap buffer with attacker controlled data, no verification or signature is validated before the vulnerability occurs." GnuPG addressed the weakness almost immediately within a day after disclosure, while urging users to  stop using  the vulnerable version. The latest version can be dow

The Best Way to Send and Receive End-to-End Encrypted Emails

March 18, 2016Swati Khandelwal
How many of you know the fact that your daily e-mails are passaged through a deep espionage filter? This was unknown until the whistleblower Edward Snowden broke all the surveillance secrets, which made privacy and security important for all Internet users than ever before. I often get asked "How to send encrypted email?", "How can I protect my emails from prying eyes?" and "Which is the best encrypted email service?". Although, there are a number of encryption tools that offers encrypted email service to ensure that no one can see what you are sending to someone else. One such tool to send encrypted emails is PGP ( Pretty Good Privacy ), an encryption tool designed to protect users' emails from snooping. However, setting up a PGP Environment for non-tech users is quite a difficult task, so more than 97% of the Internet users, including government officials, are still communicating via unencrypted email services i.e. Gmail, Ya

Werner Koch , the man who authored the free email encryption software , is running out of funding to continue the development of his crucial open-source GNU Privacy Guard (GnuPG) encryption tools.The code works on plenty of operating systems from Linux and FreeBSD to Windows and OS X. The popular Gnu Privacy Guard (GnuPG or GPG) email encryption software is the same used by the former United States National Security Agency (NSA) contractor and whistleblower Edward Snowden to keep his communication secure from law enforcement authorities. GPG uses the OpenPGP standard to safeguard the communications of millions of people, including journalists, dissidents and security-minded people, around the world from eavesdroppers and other miscreants. GPG EMAIL ENCRYPTION RELIES ON THIS GUY ONLY Werner Koch has been maintaining and improving the code of his own secure email software since its initial development in 1997, and since then he has worked at very low wages, but is now
