The msn_httpconn_parse_data function in httpconn.c in the MSN protocol plugin in libpurple in Pidgin before 2.10.0 does not properly handle HTTP 100 responses, which allows remote attackers to cause a denial of service (incorrect memory access and application crash) via vectors involving a crafted server message.

CVE-2010-4528 1 Pidgin 2 Libpurple, Pidgin 2017-09-18 4.0 MEDIUM N/A
directconn.c in the MSN protocol plugin in libpurple 2.7.6 through 2.7.8 in Pidgin before 2.7.9 allows remote authenticated users to cause a denial of service (NULL pointer dereference and application crash) via a short p2pv2 packet in a DirectConnect (aka direct connection) session.
CVE-2010-3711 1 Pidgin 1 Pidgin 2017-09-18 4.0 MEDIUM N/A
libpurple in Pidgin before 2.7.4 does not properly validate the return value of the purple_base64_decode function, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and application crash) via a crafted message, related to the plugins for MSN, MySpaceIM, XMPP, and Yahoo! and the NTLM authentication support.
CVE-2010-2528 1 Pidgin 1 Pidgin 2017-09-18 4.0 MEDIUM N/A
The clientautoresp function in family_icbm.c in the oscar protocol plugin in libpurple in Pidgin before 2.7.2 allows remote authenticated users to cause a denial of service (NULL pointer dereference and application crash) via an X-Status message that lacks the expected end tag for a (1) desc or (2) title element.
CVE-2010-0277 2 Adium, Pidgin 2 Adium, Pidgin 2017-09-18 5.0 MEDIUM N/A
slp.c in the MSN protocol plugin in libpurple in Pidgin before 2.6.6, including 2.6.4, and Adium 1.3.8 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via a malformed MSNSLP INVITE request in an SLP message, a different issue than CVE-2010-0013.
CVE-2010-0423 1 Pidgin 1 Pidgin 2017-09-18 5.0 MEDIUM N/A
gtkimhtml.c in Pidgin before 2.6.6 allows remote attackers to cause a denial of service (CPU consumption and application hang) by sending many smileys in a (1) IM or (2) chat.
CVE-2010-0420 1 Pidgin 1 Pidgin 2017-09-18 4.3 MEDIUM N/A
libpurple in Finch in Pidgin before 2.6.6, when an XMPP multi-user chat (MUC) room is used, does not properly parse nicknames containing <br> sequences, which allows remote attackers to cause a denial of service (application crash) via a crafted nickname.
CVE-2009-2694 2 Adium, Pidgin 2 Adium, Pidgin 2017-09-18 10.0 HIGH N/A
The msn_slplink_process_msg function in libpurple/protocols/msn/slplink.c in libpurple, as used in Pidgin (formerly Gaim) before 2.5.9 and Adium 1.3.5 and earlier, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) by sending multiple crafted SLP (aka MSNSLP) messages to trigger an overwrite of an arbitrary memory location. NOTE: this issue reportedly exists because of an incomplete fix for CVE-2009-1376.
CVE-2009-2703 1 Pidgin 2 Libpurple, Pidgin 2017-09-18 5.0 MEDIUM N/A
libpurple/protocols/irc/msgs.c in the IRC protocol plugin in libpurple in Pidgin before 2.6.2 allows remote IRC servers to cause a denial of service (NULL pointer dereference and application crash) via a TOPIC message that lacks a topic string.
CVE-2009-3025 1 Pidgin 1 Pidgin 2017-09-18 4.3 MEDIUM N/A
Unspecified vulnerability in Pidgin 2.6.0 allows remote attackers to cause a denial of service (crash) via a link in a Yahoo IM.
CVE-2009-3026 1 Pidgin 1 Pidgin 2017-09-18 5.0 MEDIUM N/A
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-2009-3083 1 Pidgin 2 Libpurple, Pidgin 2017-09-18 5.0 MEDIUM N/A
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-2009-3084 1 Pidgin 2 Libpurple, Pidgin 2017-09-18 5.0 MEDIUM N/A
The msn_slp_process_msg function in libpurple/protocols/msn/slpcall.c in the MSN protocol plugin in libpurple 2.6.0 and 2.6.1, as used in Pidgin before 2.6.2, allows remote attackers to cause a denial of service (application crash) via a handwritten (aka Ink) message, related to an uninitialized variable and the incorrect "UTF16-LE" charset name.
CVE-2009-3085 1 Pidgin 2 Libpurple, Pidgin 2017-09-18 5.0 MEDIUM N/A
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-2009-3615 2 Adium, Pidgin 2 Adium, Pidgin 2017-09-18 5.0 MEDIUM N/A
The OSCAR protocol plugin in libpurple in Pidgin before 2.6.3 and Adium before 1.3.7 allows remote attackers to cause a denial of service (application crash) via crafted contact-list data for (1) ICQ and possibly (2) AIM, as demonstrated by the SIM IM client.
CVE-2016-2373 3 Canonical, Debian, Pidgin 3 Ubuntu Linux, Debian Linux, Pidgin 2017-03-29 4.3 MEDIUM 5.9 MEDIUM
A denial of service vulnerability exists in the handling of the MXIT protocol in Pidgin. Specially crafted MXIT data sent via the server could potentially result in an out-of-bounds read. A malicious server or user can send an invalid mood to trigger this vulnerability.
CVE-2016-2375 3 Canonical, Debian, Pidgin 3 Ubuntu Linux, Debian Linux, Pidgin 2017-03-29 5.0 MEDIUM 5.3 MEDIUM
An exploitable out-of-bounds read exists in the handling of the MXIT protocol in Pidgin. Specially crafted MXIT contact information sent from the server can result in memory disclosure.
CVE-2016-2376 3 Canonical, Debian, Pidgin 3 Ubuntu Linux, Debian Linux, Pidgin 2017-03-29 6.8 MEDIUM 8.1 HIGH
A buffer overflow vulnerability exists in the handling of the MXIT protocol in Pidgin. Specially crafted MXIT data sent from the server could potentially result in arbitrary code execution. A malicious server or an attacker who intercepts the network traffic can send an invalid size for a packet which will trigger a buffer overflow.
CVE-2016-2377 3 Canonical, Debian, Pidgin 3 Ubuntu Linux, Debian Linux, Pidgin 2017-03-29 6.8 MEDIUM 8.1 HIGH
A buffer overflow vulnerability exists in the handling of the MXIT protocol in Pidgin. Specially crafted MXIT data sent by the server could potentially result in an out-of-bounds write of one byte. A malicious server can send a negative content-length in response to a HTTP request triggering the vulnerability.
