Francis Provencher has discovered a vulnerability in the FlashPix PlugIn for IrfanView, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to insufficient validation when decompressing FlashPix images and can be exploited to cause a heap-based buffer overflow via a specially crafted FPX file.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is confirmed in version 4.3.2.0. Other versions may also be affected.

You state that the solution for this is to update to v4.3.4...and yet no such version exists yet on the Secunia site??

Sadly, genuine submissions created on this Forum are getting "lost" amongst the sustained spammer attack posts being created.

I have grouped this post & others where Forum members have open questions & comments which should make it easier for Forum readers & helpers to navigate.

I meant of course to say that v4.3.4 is not available on the Irfanview site.

ddmarshall's link to the plugin page just shows v 4.3.3

You didn't read far enough down

PlugIns updated after the version 4.33:


FPX/FlashPix PlugIn (4.34): Installer or ZIP - FPX-Library loading bug fixed (reported by Francis Provencher via Secunia SVCRP, thanks!)

XCF PlugIn (1.08): Installer or ZIP - Some loading bugs fixed (reported by FuzzMyApp, thanks!)

You are right! My wife has alawys said that I'm crap at looking. ;-)

Not particularly clear by IrfanView though...the top of that page clearly states that 4.33 is the latest version.
Anyway...thanks!
