Published:14.09.2009
Source:
SecurityVulns ID:10235
Type:library
Threat Level:
7/10
Description:Multiple vulnerabilities on MSN, Yahoo IM, IRC, jabber protocol parsing.
Affected:LIBPURPLE : libpurple 2.6
 PIDGIN : Pidgin 2.6
CVE:CVE-2009-3085 (The XMPP protocol plugin in libpurple in Pidgin before 2.6.2 does not properly handle an error IQ stanza during an attempted fetch of a custom smiley, which allows remote attackers to cause a denial of service (application crash) via XHTML-IM content with cid: images.)
 CVE-2009-3083 (The msn_slp_sip_recv function in libpurple/protocols/msn/slp.c in the MSN protocol plugin in libpurple in Pidgin before 2.6.2 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an SLP invite message that lacks certain required fields, as demonstrated by a malformed message from a KMess client.)
 CVE-2009-3026 (protocols/jabber/auth.c in libpurple in Pidgin 2.6.0, and possibly other versions, does not follow the "require TLS/SSL" preference when connecting to older Jabber servers that do not follow the XMPP specification, which causes libpurple to connect to the server without the expected encryption and allows remote attackers to sniff sessions.)
 CVE-2009-3025 (Unspecified vulnerability in Pidgin 2.6.0 allows remote attackers to cause a denial of service (crash) via a link in a Yahoo IM.)
