Description Jan Lieskovsky 2009-05-21 11:30:00 UTC

The Wireshark's PCNFSD dissector, dissecting records of network traffic
from an RPC server that supports ONC clients on PC (DOS, OS/2, Macintosh, and other) systems, could crash.

Versions affected: 0.8.20 to 1.0.7

Upstream patch against 1.0.*:
http://anonsvn.wireshark.org/viewvc?view=rev&revision=28404 -- part:

r28128 | gerald | 2009-04-22 10:42:47 -0700 (Wed, 22 Apr 2009) | 6 lines
Changed paths:
   M /trunk/epan/dissectors/packet-pcnfsd.c
   M /trunk/epan/dissectors/packet-rpc.c
   M /trunk/epan/dissectors/packet-rpc.h

From Mark Cave-Ayland: Fix a crash in the PCNFSD dissector.

From me: Apply Mark's fix to the ident string. Add public #defines for
the special strings that dissect_rpc_* might return and use them in
PCNFSD.  Replace a manual buffer allocation with ep_strdup_printf.

i.e.
