A remote overflow exists in Netscape Navigator. The issue is due to improper bounds checking of the npcdt.dll plug-in resulting in a buffer overflow. By creating a malicious file with an overly long file name, an attacker can cause arbitrary code execution, resulting in a loss of integrity.
Currently, there are no known upgrades or patches to correct this issue. It is possible to correct the flaw by implementing the following workaround: Remove the affected plug-in (npcdt.dll) from the 'components' Netscape folder.
