3. Description:

The libsoup packages provide an HTTP client and server library for GNOME.

Security Fix(es):

* A stack-based buffer overflow flaw was discovered within the HTTP
processing of libsoup. A remote attacker could exploit this flaw to cause a
crash or, potentially, execute arbitrary code by sending a specially
crafted HTTP request to a server using the libsoup HTTP server
functionality or by tricking a user into connecting to a malicious HTTP
server with an application using the libsoup HTTP client functionality.
(CVE-2017-2885)

Red Hat would like to thank Aleksandar Nikolic (Cisco Talos) for reporting
this issue.
