Description

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.

Affected products

Pidgin: through 2.5.5; 2.4.0-32_bit, 2.4.1-32_bit, 2.4.2-32_bit, 2.4.3-32_bit, 2.5.0-32_bit, 2.5.2-32_bit (+2)
