CVE-2009-2694
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.");
