## Description

The nsTextFrame::ClearTextRun function in
layout/generic/nsTextFrameThebes.cpp in Mozilla Firefox 3.0.9 allows remote
attackers to cause a denial of service (memory corruption) and probably
execute arbitrary code via unspecified vectors. NOTE: this vulnerability
reportedly exists because of an incorrect fix for CVE-2009-1302.
