Vulnerability Name:

CCN-40992

Published:2008-03-27
Updated:2008-03-27
Summary:WebKit could allow a remote attacker to execute arbitrary code on the system, caused by an error in the calculateCompiledPatternLength() function. An attacker could exploit this vulnerability via regular expressions with large nested repetition counts to execute arbitrary code with the privileges of the application.
