TITLE:
Wireshark Multiple Denial of Service Vulnerabilities

SECUNIA ADVISORY ID:
SA27777

VERIFY ADVISORY:
http://secunia.com/advisories/27777/

CRITICAL:
Moderately critical

IMPACT:
DoS

WHERE:
>From remote

REVISION:
1.1 originally posted 2007-11-22

SOFTWARE:
Wireshark (formerly Ethereal) 0.x
http://secunia.com/product/1228/

DESCRIPTION:
Some vulnerabilities have been reported in Wireshark, which can be
exploited by malicious people to cause a DoS (Denial of Service).

The vulnerabilities are caused due to various errors (e.g. large
loops with extreme memory consumption, endless loops, crashes, and
buffer overflows) within the following:
* SSL, ANSI MAP, Firebird/Interbase, NCP, HTTP, MEGACO, DCP ETSI,
PPP, and Bluetooth SDP dissectors
* when processing a malformed MP3 or iSeries (OS/400) Communication
trace file
* when processing a malformed DNP or RPC Portmap packet

These can be exploited to crash Wireshark or consume large amounts of
system resources by e.g. parsing a specially crafted packet that is
either captured off the wire or loaded via a capture file.

The vulnerabilities are reported in various versions from 0.8.16
through 0.99.6. Other versions may also be affected.

SOLUTION:
The vulnerabilities are fixed in the upcoming version 0.99.7.

PROVIDED AND/OR DISCOVERED BY:
Stefan Esser (SSL dissector)
Beyond Security (DNP packet)
Fabiodds (iSeries (OS/400) Communication trace file)
Peter Leeming (ANSI MAP)
Steve (Firebird/Interbase)
ainsley (RPC Portmap)
