Description
The XSSAuditor::canonicalize function in core/html/parser/XSSAuditor.cpp in the XSS auditor in Blink, as used in Google Chrome before 44.0.2403.89, does not properly choose a truncation point, which makes it easier for remote attackers to obtain sensitive information via an unspecified linear-time attack.
