  script_tag(name:"insight", value:"The curl packages provide the libcurl library and the curl utility for
downloading files from servers using various protocols, including HTTP,
FTP, and LDAP.

It was found that the libcurl library did not correctly handle partial
literal IP addresses when parsing received HTTP cookies. An attacker able
to trick a user into connecting to a malicious server could use this flaw
to set the user's cookie to a crafted domain, making other cookie-related
issues easier to exploit. (CVE-2014-3613)

A flaw was found in the way the libcurl library performed the duplication
of connection handles. If an application set the CURLOPT_COPYPOSTFIELDS
option for a handle, using the handle's duplicate could cause the
application to crash or disclose a portion of its memory. (CVE-2014-3707)

It was discovered that the libcurl library failed to properly handle URLs
with embedded end-of-line characters. An attacker able to make an
application using libcurl to access a specially crafted URL via an HTTP
proxy could use this flaw to inject additional headers to the request or
construct additional requests. (CVE-2014-8150)

It was discovered that libcurl implemented aspects of the NTLM and
Negotiate authentication incorrectly. If an application uses libcurl
and the affected mechanisms in a specific way, certain requests to a
previously NTLM-authenticated server could appears as sent by the wrong
authenticated user. Additionally, the initial set of credentials for HTTP
Negotiate-authenticated requests could be reused in subsequent requests,
although a different set of credentials was specified. (CVE-2015-3143,
CVE-2015-3148)

Red Hat would like to thank the cURL project for reporting these issues.

Bug fixes:

  * An out-of-protocol fallback to SSL version 3.0 (SSLv3.0) was available
with libcurl. Attackers could abuse the fallback to force downgrade of the
SSL version. The fallback has been removed from libcurl. Users requiring
this functionality can explicitly enable SSLv3.0 through the libcurl API.
(BZ#1154059)

  * A single upload transfer through the FILE protocol opened the destination
file twice. If the inotify kernel subsystem monitored the file, two events
were produced unnecessarily. The file is now opened only once per upload.
(BZ#883002)

  * Utilities using libcurl for SCP/SFTP transfers could terminate
unexpectedly when the system was running in FIPS mode. (BZ#1008178)

  * Using the '--retry' option with the curl utility could cause curl to
terminate unexpectedly with a segmentation fault. Now, adding ...
