+Subject: [PATCH 1/2] rpm: CVE-2014-8118
+
+Upstream-Status: Backport
+
+Reference:
+https://bugzilla.redhat.com/show_bug.cgi?id=1168715
+
+Description:
+It was found that RPM could encounter an integer overflow,
+leading to a stack-based overflow, while parsing a crafted
+CPIO header in the payload section of an RPM file. This could
+allow an attacker to modify signed RPM files in such a way that
+they would execute code chosen by the attacker during package
+installation.
+
+Original Patch:
+https://bugzilla.redhat.com/attachment.cgi?id=962159
