SecurityAlert : 535

CVE : CVE-2006-1091

SecurityRisk : Medium Security Risk Medium

(About)

Remote Exploit : Yes

Local Exploit : No

Exploit Given : Yes

Credit : Michael Lang jackal-net at

Published : 05.03.2006

Affected Software :

Kaspersky AV Scanner x<= 5.5.3

Advisory Text :

Hi,

i've recently discovered a design problem in Kaspersky AV Scanner. Original
seen on FileScanner for Unix 5.0.5 the Problematic files are also screewing
up the latest 5.5.3 Version.

AS i didnt find an offical way to deploy this at Kaspersky i hope someone
from them will read this
and contact me to get a POC.

Therefore not all details will be shown here to avoid massive attacks.
The file(s) are 1.6M of size and dont contain suspicous content.

calling 3 kavscanner instances already renders a P4 2.4Ghz Machine with
512Mb Ram useless after a few seconds.
A POC flashcapture is located at
http://www.jackal-net.at/KasperskyLeakPOC.swf

did anyone else encountered a similar problem ?
ClamAV works fine on the same Files.

Kind Regards
Michael Lang
