Multiple security vulnerabilities has been identified and fixed in gaim: Buffer overflow in the XMPP SOCKS5 bytestream server in Pidgin before 2.5.6 allows remote authenticated users to execute arbitrary code via vectors involving an outbound XMPP file transfer. NOTE: some of these details are obtained from third party information (CVE-2009-1373). 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 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 (CVE-2009-1376). The updated packages have been patched to prevent this. Affected: Corporate 3.0
