On Wednesday, William Carrel posted an advisory warning of a malicious DHCP response that can grant root access for Mac OS X. The vulnerability affects the desktop and server versions of Mac OS X 10.2, known as Jaguar, as well as Mac OS X 10.3, known as Panther, he wrote.
Separately, Copenhagen, Denmark-based security company Secunia issued a security advisory late Tuesday about five security vulnerabilities in Internet Explorer 6.0 and possibly in earlier versions of the browser as well. Together, they "can be exploited to compromise a user's system" the advisory warns.
In addition, Secunia late last week also found vulnerabilities in the Opera browser, Version 7.22 and earlier, that can cause a buffer overflow. Opera this week released an update to its browser, Opera 7.23, that fixes the holes.
