GnuPG before 1.4.19 is vulnerable to a side-channel attack on data-dependent
timing variations in modular exponentiation, which can potentially lead to an
information leak (CVE-2015-0837).

The gnupg package has been patched to correct these issues.

GnuPG2 is vulnerable to these issues through the libgcrypt library. The
issues were fixed in libgcrypt 1.6.3. The libgcrypt package in Mageia,
at version 1.5.4, was only vulnerable to the CVE-2014-3591 issue. It has
also been patched to correct this issue.");
