CVE-2009-2694

pidgin: insufficient input validation in msn_slplink_process_msg()

Published Aug 20, 2009 CVSS 2.0 · 10.0 Critical EPSS 20.3% KEV · Not listed
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.
