Multiple integer overflows in the msn_slplink_process_msg functions in the MSN protocol handler in (1) libpurple/protocols/msn/slplink.c and (2) libpurple/protocols/msnp9/slplink.c in Pidgin (formerly Gaim) before 2.5.6 on 32-bit platforms allow remote attackers to execute arbitrary code via a malformed SLP message with a crafted offset value, leading to buffer overflows. NOTE: this issue exists because of an incomplete fix for CVE-2008-2927.

Security readout for executives and security teams

CVE-2009-1376 affects older Pidgin/libpurple MSN messaging support on 32-bit platforms. A specially malformed MSN SLP message could corrupt memory and potentially let a remote attacker run code as the user. The issue is old, but legacy clients or embedded libpurple deployments may still matter. Exposure is most likely in legacy 32-bit systems running Pidgin, Gaim-era packages, or applications embedding vulnerable libpurple MSN protocol code before 2.5.6. Treat as high priority only where legacy 32-bit Pidgin/libpurple remains in use. For modern environments without those clients or MSN protocol support, business urgency is low but should be confirmed by inventory. Mitigation focus: Upgrade Pidgin/libpurple to 2.5.6 or a vendor-patched package.; Prioritize legacy 32-bit endpoints and servers with libpurple-based messaging integrations.; Disable MSN protocol handling where patching is delayed or the protocol is unused..
