CVE-2011-1425 xmlsec1: arbitrary file creation when verifying signatures
Last modified: 2013-04-03 16:18:22 EDT
Nicolas Grégoire discovered that xmlsec1 can create a file with attacker-specified path name and content when xmlsec1 is used to verify a signature of a specially-crafted XML file specifying XSLT transformation. This may be used to create or overwrite arbitrary file writeable to the user running xmlsec1.
This issue was addressed upstream via following commit, which disables XSLT read/write by default:
Red Hat would like to thank Nicolas Grégoire and Aleksey Sanin for reporting this issue.
