CAN-2004-1316 buffer overflow in mozilla
Last modified: 2007-11-30 17:10:57 EST
As reported on secunia
Maurycy Prodeus has reported a vulnerability in Mozilla, which can be exploited
by malicious people to cause a DoS (Denial of Service) and potentially
compromise a user's system.
The vulnerability is caused due to a boundary error in the
"MSG_UnEscapeSearchUrl()" function in "nsNNTPProtocol.cpp" when processing NNTP
URIs. This can be exploited via e.g. a malicious web site to cause a heap-based
buffer overflow when referencing a specially crafted, overly long "news://" URI.
Successful exploitation crashes the application, but may potentially allow
execution of arbitrary code.
The vulnerability has been reported in version 1.7.3 and prior.
This issue should also affect FC2
Over to caillon.
Fixed in latest mozilla release version.
