This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

libxslt 1.1.26 and earlier, as used in Google Chrome before 21.0.1180.89, does not properly manage memory, which might allow remote attackers to cause a denial of service (application crash) via a crafted XSLT expression that is not properly identified during XPath navigation, related to (1) the xsltCompileLocationPathPattern function in libxslt/pattern.c and (2) the xsltGenerateIdFunction function in libxslt/functions.c.

The weakness was presented 09/18/2013 by Nicolas Gregoire (miaubiz) with Google Security Team as APPLE-SA-2013-09-18-2 iOS 7 as confirmed mailinglist post (Website). The advisory is available at prod.lists.apple.com. The mailinglist post contains:

Multiple memory corruption issues existed in libxslt. These issues were addressed by updating libxslt to version 1.1.28.
