Debian: DSA-3185-1: libgcrypt11 security update
Summary
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.
For the stable distribution (wheezy), these problems have been fixed in
version 1.5.0-5+deb7u3.
We recommend that you upgrade your libgcrypt11 packages.
