Multiple vulnerabilities were discovered in libgcrypt :
CVE-2014-3591
The Elgamal decryption routine was susceptible to a side-channel attack discovered by researchers of Tel Aviv University. Ciphertext blinding was enabled to counteract it. Note that this may have a quite noticeable impact on Elgamal decryption performance.
CVE-2015-0837
The modular exponentiation routine mpi_powm() was susceptible to a side-channel attack caused by data-dependent timing variations when accessing its internal pre-computed table.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
