Package        : libgcrypt11
Version        : 1.4.5-2+squeeze3
CVE ID         : CVE-2014-3591 CVE-2015-0837

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.

     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.
