CVE-2009-3084 1 Pidgin 2 Libpurple, Pidgin 2025-04-09 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-2009-3026 2 Pidgin, Redhat 2 Pidgin, Enterprise Linux 2025-04-09 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-2009-2703 2 Pidgin, Redhat 3 Libpurple, Pidgin, Enterprise Linux 2025-04-09 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-2009-2694 3 Adium, Pidgin, Redhat 3 Adium, Pidgin, Enterprise Linux 2025-04-09 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-2009-2404 5 Aol, Gnome, Mozilla and 2 more 9 Instant Messenger, Evolution, Firefox and 6 more 2025-04-09 N/A
Heap-based buffer overflow in a regular-expression parser in Mozilla Network Security Services (NSS) before 3.12.3, as used in Firefox, Thunderbird, SeaMonkey, Evolution, Pidgin, and AOL Instant Messenger (AIM), allows remote SSL servers to cause a denial of service (application crash) or possibly execute arbitrary code via a long domain name in the subject's Common Name (CN) field of an X.509 certificate, related to the cert_TestHostName function.
CVE-2022-26491 2 Debian, Pidgin 2 Debian Linux, Pidgin 2024-11-21 5.9 Medium
An issue was discovered in Pidgin before 2.14.9. A remote attacker who can spoof DNS responses can redirect a client connection to a malicious server. The client will perform TLS certificate verification of the malicious domain name instead of the original XMPP service domain, allowing the attacker to take over control over the XMPP connection and to obtain user credentials and all communication content. This is similar to CVE-2022-24968.
CVE-2017-2640 3 Debian, Pidgin, Redhat 8 Debian Linux, Pidgin, Enterprise Linux and 5 more 2024-11-21 N/A
An out-of-bounds write flaw was found in the way Pidgin before 2.12.0 processed XML content. A malicious remote server could potentially use this flaw to crash Pidgin or execute arbitrary code in the context of the pidgin process.
CVE-2016-1000030 2 Pidgin, Suse 2 Pidgin, Linux Enterprise Server 2024-11-21 N/A
Pidgin version <2.11.0 contains a vulnerability in X.509 Certificates imports specifically due to improper check of return values from gnutls_x509_crt_init() and gnutls_x509_crt_import() that can result in code execution. This attack appear to be exploitable via custom X.509 certificate from another client. This vulnerability appears to have been fixed in 2.11.0.
CVE-2012-1257 1 Pidgin 1 Pidgin 2024-11-21 5.5 Medium
Pidgin 2.10.0 uses DBUS for certain cleartext communication, which allows local users to obtain sensitive information via a dbus session monitor.
