Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

Updated gnupg and libgcrypt packages fix security vulnerabilities :

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
Mandriva, at version 1.5.4, was only vulnerable to the CVE-2014-3591
issue. It has also been patched to correct this issue.
