Issue Overview:
libcurl’s implementation of the printf() functions triggers a buffer overflow when doing a large floating point output. If there are any application that accepts a format string from the outside without necessary input filtering, it could allow remote attacks. This flaw does not exist in the command line tool.
Affected Packages:
curl
Issue Correction:
Run yum update curl to update your system.
