[slackware-security] curl (SSA:2013-038-01)

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 *)
