## Description

The msn\_slplink\_process\_msg function in libpurple/protocols/msn/slplink.c
in libpurple, as used in Pidgin (formerly Gaim) before 2.5.9 and Adium
1.3.5 and earlier, allows remote attackers to execute arbitrary code or
cause a denial of service (memory corruption and application crash) by
sending multiple crafted SLP (aka MSNSLP) messages to trigger an overwrite
of an arbitrary memory location. NOTE: this issue reportedly exists
because of an incomplete fix for CVE-2009-1376.
