CVSS v3.1 |
| 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. |
| The Mxit protocol uses weak encryption when encrypting user passwords, which might allow attackers to (1) decrypt hashed passwords by leveraging knowledge of client registration codes or (2) gain login access by eavesdropping on login messages and re-using the hashed passwords. |
| The jabber_idn_validate function in jutil.c in the Jabber protocol plugin in libpurple in Pidgin before 2.10.10 allows remote attackers to obtain sensitive information from process memory via a crafted XMPP message. |
| Absolute path traversal vulnerability in the untar_block function in win32/untar.c in Pidgin before 2.10.10 on Windows allows remote attackers to write to arbitrary files via a drive name in a tar archive of a smiley theme. |
| nmevent.c in the Novell GroupWise protocol plugin in libpurple in Pidgin before 2.10.10 allows remote servers to cause a denial of service (application crash) via a crafted server message that triggers a large memory allocation. |
| The (1) bundled GnuTLS SSL/TLS plugin and the (2) bundled OpenSSL SSL/TLS plugin in libpurple in Pidgin before 2.10.10 do not properly consider the Basic Constraints extension during verification of X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate. |
| markup.c in the MXit protocol plugin in libpurple in Pidgin before 2.10.10 allows remote servers to cause a denial of service (application crash) via a large length value in an emoticon response. |
| family_feedbag.c in the oscar protocol plugin in libpurple in Pidgin before 2.10.1 does not perform the expected UTF-8 validation on message data, which allows remote attackers to cause a denial of service (application crash) via a crafted (1) AIM or (2) ICQ message associated with buddy-list addition. |
| The notify function in pidgin-knotify.c in the pidgin-knotify plugin 0.2.1 and earlier for Pidgin allows remote attackers to execute arbitrary commands via shell metacharacters in a message. |
| libymsg.c in the Yahoo! protocol plugin in libpurple in Pidgin 2.6.0 through 2.7.10 allows (1) remote authenticated users to cause a denial of service (NULL pointer dereference and application crash) via a malformed YMSG notification packet, and allows (2) remote Yahoo! servers to cause a denial of service (NULL pointer dereference and application crash) via a malformed YMSG SMS message. |
| 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. |
| upnp.c in libpurple in Pidgin before 2.10.7 does not properly terminate long strings in UPnP responses, which allows remote attackers to cause a denial of service (application crash) by leveraging access to the local network. |
| The IRC protocol plugin in libpurple in Pidgin before 2.10.8 does not validate argument counts, which allows remote IRC servers to cause a denial of service (application crash) via a crafted message. |
| The silc_channel_message function in ops.c in the SILC protocol plugin in libpurple in Pidgin before 2.10.1 does not perform the expected UTF-8 validation on message data, which allows remote attackers to cause a denial of service (application crash) via a crafted message, a different vulnerability than CVE-2011-3594. |
| cipher.c in the Cipher API in libpurple in Pidgin before 2.7.10 retains encryption-key data in process memory, which might allow local users to obtain sensitive information by reading a core file or other representation of memory contents. |
| The pidgin_conv_chat_rename_user function in gtkconv.c in Pidgin before 2.10.2 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) by changing a nickname while in an XMPP chat room. |
| gtkutils.c in Pidgin before 2.10.0 on Windows allows user-assisted remote attackers to execute arbitrary programs via a file: URL in a message. |
| gtkimhtml.c in Pidgin before 2.10.8 does not properly interact with underlying library support for wide Pango layouts, which allows user-assisted remote attackers to cause a denial of service (application crash) via a long URL that is examined with a tooltip. |
| util.c in libpurple in Pidgin before 2.10.8 does not properly allocate memory for HTTP responses that are inconsistent with the Content-Length header, which allows remote HTTP servers to cause a denial of service (application crash) via a crafted response. |
| libpurple/protocols/yahoo/libymsg.c in Pidgin before 2.10.8 allows remote attackers to cause a denial of service (crash) via a Yahoo! P2P message with a crafted length field, which triggers a buffer over-read. |
