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.
