Package : libgcrypt11
Version : 1.5.0-5+deb7u5
CVE ID : CVE-2016-6313
The crypto library libgcrypt11 has a weakness in the random number
generator.
CVE-2016-6313
Felix Dörre and Vladimir Klebanov from the Karlsruhe Institute of
Technology found a bug in the mixing functions of Libgcrypt's random
number generator. An attacker who obtains 4640 bits from the RNG can
trivially predict the next 160 bits of output.
A first analysis on the impact of this bug in GnuPG shows that existing
RSA keys are not weakened. For DSA and Elgamal keys it is also unlikely
that the private key can be predicted from other public information.
For Debian 7 "Wheezy", these problems have been fixed in version
1.5.0-5+deb7u5.
We recommend that you upgrade your libgcrypt11 packages.
