Synopsis
========

Multiple vulnerabilities have been fixed in libgcrypt,the worst of
which results in predictable output from the random number generator.

Background
==========

libgcrypt is a general purpose cryptographic library derived out of
GnuPG.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-libs/libgcrypt < 1.7.3 >= 1.7.3

Description
===========

Multiple vulnerabilities have been discovered in libgcrypt. Please
review the CVE identifiers referenced below for details.

Impact
======

Side-channel attacks can leak private key information. A separate
critical bug allows an attacker who obtains 4640 bits from the RNG to
trivially predict the next 160 bits of output.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All libgcrypt users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/libgcrypt-1.7.3"
