Same here after version 4.2.
It appears only on plugins to be updated too…
Update manually.
To resolve is quite simple, as there is the option to update the plugin with this alert covering, then you should mark it, and click update.
There, the alert disappears and the plugin is updated.
Thanks! That works.
But didn’t resolved the function problem.

The error is the official version of wordpress.
To fix temporarily while they do not, do the following:
Go to the folder
/wp-admin/includes
Open the file update.php
change the line 289 of that here:
printf( __( 'There is a new version of %1$s available. <a href="%2$s" title="%3$s">View version %4$s details</a> or <a href="%5$s">update now</a>.' ), $plugin_name, esc_url( $details_url ), esc_attr( $plugin_name ), $r->new_version, wp_nonce_url( self_admin_url( 'update.php?action=upgrade-plugin&plugin=' ) . $file, 'upgrade-plugin_' . $file ) );
for it here:
printf( __( 'There is a new version of %1$s available. <a href="%2$s" title="%3$s">View version %4$s details</a>.' ), $plugin_name, esc_url( $details_url ), esc_attr( $plugin_name ), $r->new_version, wp_nonce_url( self_admin_url( 'update.php?action=upgrade-plugin&plugin=' ) . $file, 'upgrade-plugin_' . $file ) );
Save the file and test the plugins page that will back up and running

I do not speak in English I used google translator!
In this case is not necessary the use of “%[num]$s” for the function printf() “%s” is enough. And the problem is the 5th parameter. So just replace the line 289 for this:
printf( __( 'There is a new version of %s available. <a href="%s" class="thickbox" title="%s">View version %s details</a> or <a href="%s" class="update-link">update now</a>.' ),
$plugin_name, esc_url( $details_url ), esc_attr( $plugin_name ), $r->new_version, wp_nonce_url( self_admin_url( 'update.php?action=upgrade-plugin&plugin=' ) . $file, 'upgrade-plugin_' . $file ) );
