Researchers Crack 1024-bit RSA Encryption in GnuPG Crypto Library
|
|
Security boffins have discovered a critical vulnerability in a GnuPG cryptographic library that allowed the researchers to completely break RSA-1024 and successfully extract the secret RSA key to decrypt data. Gnu Privacy Guard (GnuPG or GPG) is popular open source encryption software used by many operating systems from Linux and FreeBSD to Windows and macOS X. It's the same software used by the former NSA contractor and whistleblower Edward Snowden to keep his communication secure from law enforcement. The vulnerability, labeled CVE-2017-7526, resides in the Libgcrypt cryptographic library used by GnuPG, which is prone to local FLUSH+RELOAD side-channel attack.
