| CVE-2009-2694 | 2 Adium, Pidgin | 2 Adium, Pidgin | 2026-04-23 | 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-2009-3084 | 1 Pidgin | 2 Libpurple, Pidgin | 2026-04-23 | 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-2009-3026 | 1 Pidgin | 1 Pidgin | 2026-04-23 | 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 | 2026-04-23 | 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-2019-25544 | 1 Pidgin | 1 Pidgin | 2026-04-16 | N/A | 6.2 MEDIUM |
| Pidgin 2.13.0 contains a denial of service vulnerability that allows local attackers to crash the application by providing an excessively long username string during account creation. Attackers can input a buffer of 1000 characters in the username field and trigger a crash when joining a chat, causing the application to become unavailable. | |||||
| CVE-2016-2378 | 3 Canonical, Debian, Pidgin | 3 Ubuntu Linux, Debian Linux, Pidgin | 2025-04-20 | 6.8 MEDIUM | 8.1 HIGH |
| A buffer overflow vulnerability exists in the handling of the MXIT protocol Pidgin. Specially crafted data sent via the server could potentially result in a buffer overflow, potentially resulting in memory corruption. A malicious server or an unfiltered malicious user can send negative length values to trigger this vulnerability. | |||||
| CVE-2016-2367 | 3 Canonical, Debian, Pidgin | 3 Ubuntu Linux, Debian Linux, Pidgin | 2025-04-20 | 3.5 LOW | 5.9 MEDIUM |
| An information leak 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 user, server, or man-in-the-middle can send an invalid size for an avatar which will trigger an out-of-bounds read vulnerability. This could result in a denial of service or copy data from memory to the file, resulting in an information leak if the avatar is sent to another user. | |||||
| CVE-2016-2370 | 3 Canonical, Debian, Pidgin | 3 Ubuntu Linux, Debian Linux, Pidgin | 2025-04-20 | 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 from the server could potentially result in an out-of-bounds read.

| An exploitable memory corruption vulnerability exists in the handling of the MXIT protocol in Pidgin. Specially crafted MXIT MultiMX message sent via the server can result in an out-of-bounds write leading to memory disclosure and code execution. | |||||
| CVE-2016-2365 | 3 Canonical, Debian, Pidgin | 3 Ubuntu Linux, Debian Linux, Pidgin | 2025-04-20 | 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 a null pointer dereference.

| CVE-2016-2377 | 3 Canonical, Debian, Pidgin | 3 Ubuntu Linux, Debian Linux, Pidgin | 2025-04-20 | 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. | |||||
| CVE-2016-2375 | 3 Canonical, Debian, Pidgin | 3 Ubuntu Linux, Debian Linux, Pidgin | 2025-04-20 | 5.0 MEDIUM | 5.3 MEDIUM |
