    Summary: Updated gnupg and libgcrypt packages fix security vulnerabilities

    Details: GnuPG before 1.4.19 is vulnerable to a side-channel attack which can potentially lead to an information leak (CVE-2014-3591). 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.
