Wolfgang Kandek, CTO of Qualys, confirms that switching to another browser like Chrome is sufficient to protect Windows XP in this case. "Chrome does not support one of the required formats (VML) so it should not be effected, even if the vulnerable DLL is on the machine."
In fact, regardless of this particular zero day flaw, it's just a good idea to switch to a supported browser like Firefox or Chrome for the duration of your remaining days on Windows XP. There's no point in willingly putting your PC at more risk than you are just by choosing to continue using an unsupported operating system.
"Switching to Chrome or Firefox will enable XP users to remove the relevant attack surface, says Kurt Baumgartner, principal security researcher at Kaspersky Lab. "But they shouldn't be using XP in the first place — move off of XP people!"
Storms echoes the sentiment. He points out that Windows XP users should be gravely concerned that this issue will never be patched for their OS. Storms stressed that a greater concern than this specific vulnerability is the fact that Windows XP is an outdated operating system and it will soon have many more security problems to contend with.
The best word of advice to XP users is to upgrade.
