Responding to the disclosure of a serious Web browser flaw, the Mozilla Foundation offered on Friday a temporary fix to protect Firefox and Mozilla users.
The downloadable fix protects against attacks that take advantage of a new, unpatched flaw that could let attackers secretly run malicious software on users' PCs. The flaw was disclosed late Thursday by security researcher Tom Ferris, sending Mozilla staff into damage-control mode.
The problem has to do with the way the Firefox and Mozilla browsers handle International Domain Names, or IDNs, said Mike Schroepfer, director of engineering at Mozilla. IDNs are domain names that use local language characters. The fix disables support for such Web addresses, he said.
