Microsoft released an updated and fixed version of Service Pack 1 (SP1) for SharePoint 2013 on April 22.
A list of all the new associated Knowledge Base articles on the updated SP1s for SharePoint Foundation 2013, SharePoint Server 2013, Project Server 2013, and Office Web Apps Server 2013 are available from this TechNet blog post.
The post notes that these KB articles are different from those associated with the recalled SP1. Customers who previously deployed SharePoint 2013 SP1 are advised to download the updated SP1 and install it over the existing SP1. Customers who didn't deploy the original SP1 bits should just use the uploaded bits.

Microsoft released SP1 for SharePoint Server 2013 in late February. SP1 introduced compatibility with Windows Server 2012 R2, plus support for connecting to OneDrive for Business, as well as Yammer integration.
By early April, Microsoft withdrew SP1 for SharePoint 2013 due to problems some users were having in getting cumulative updates after applying the service pack, according to Microsoft officials.
The updated SharePoint 2013 SP1 (which is dated April 17, as Redmond Magazine noted), includes previously unreleased fixes, plus a fix for a missing search box issue.
