 Mandriva Linux Security Advisory                         MDVSA-2009:173
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : pidgin
 Date    : July 29, 2009
 Affected: Enterprise Server 5.0
 _______________________________________________________________________

 Problem Description:

 Security vulnerabilities has been identified and fixed in pidgin:
 
 Buffer overflow in the XMPP SOCKS5 bytestream server in Pidgin
 (formerly Gaim) 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).
 
 Buffer overflow in the decrypt_out function in Pidgin (formerly Gaim)
 before 2.5.6 allows remote attackers to cause a denial of service
 (application crash) via a QQ packet (CVE-2009-1374).
 
 The PurpleCircBuffer implementation in Pidgin (formerly Gaim) before
 2.5.6 does not properly maintain a certain buffer, which allows
 remote attackers to cause a denial of service (memory corruption
 and application crash) via vectors involving the (1) XMPP or (2)
 Sametime protocol (CVE-2009-1375).
 
 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 (CVE-2009-1376).
 
 This update provides pidgin 2.5.8, which is not vulnerable to these
 issues.
