New curl packages are available for Slackware 14.0, and -current to
fix a security issue.

Here are the details from the Slackware 14.0 ChangeLog:
patches/packages/curl-7.29.0-i486-1_slack14.0.txz:  Upgraded.
  When negotiating SASL DIGEST-MD5 authentication, the function
  Curl_sasl_create_digest_md5_message() uses the data provided from the
  server without doing the proper length checks and that data is then
  appended to a local fixed-size buffer on the stack.  This vulnerability
  can be exploited by someone who is in control of a server that a libcurl
  based program is accessing with POP3, SMTP or IMAP.  For applications
  that accept user provided URLs, it is also thinkable that a malicious
  user would feed an application with a URL to a server hosting code
  targeting this flaw.
  Affected versions: curl 7.26.0 to and including 7.28.1
  For more information, see:
  (* Security fix *)
