3. Description:

The curl packages provide the libcurl library and the curl utility for
downloading files from servers using various protocols, including HTTP,
FTP, and LDAP.

Security Fix(es):

* A buffer overrun flaw was found in the IMAP handler of libcurl. By
tricking an unsuspecting user into connecting to a malicious IMAP server,
an attacker could exploit this flaw to potentially cause information
disclosure or crash the application. (CVE-2017-1000257)

Red Hat would like to thank the Curl project for reporting this issue.
Upstream acknowledges Brian Carpenter and the OSS-Fuzz project as the
original reporters.
