Description Tomas Hoger 2010-01-05 05:06:37 EST
On 26C3, Fabian Yamaguchi presented a directory traversal flaw in libpurple MSN protocol implementation.  The flaw can be used by the remote attacker to download arbitrary file readable by the user running instant messenger using libpurple (such as pidgin) from the victim's computer via MSN emoticon / smiley download request.  More details in Fabian's presentation:

Mitigations:
Remove ~/.purple/custom_smiley/ directory if it exists.  The directory is not created by default and is created when first custom smiley is defined.
