Description Florian Weimer 2014-11-27 16:07:33 UTC 
IssueDescription:

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.

Acknowledgements:

This issue was discovered by Florian Weimer of Red Hat Product Security.
