| <background> |
| <p> |
| Pidgin is a client for a variety of instant messaging protocols. |
| </p> |
| </background> |
| <description> |
| <p> |
| Multiple vulnerabilities were found in Pidgin: |
| </p> |
| <ul> |
| <li>Yuriy |
| Kaminskiy reported that the OSCAR protocol implementation in Pidgin |
| misinterprets the ICQWebMessage message type as the ICQSMS message |
| type, triggering an allocation of a large amount of memory |
| (CVE-2009-1889).</li> |
| <li>Federico Muttis of Core Security Technologies |
| reported that the msn_slplink_process_msg() function in |
| libpurple/protocols/msn/slplink.c in libpurple as used in Pidgin |
| doesn't properly process incoming SLP messages, triggering an overwrite |
| of an arbitrary memory location (CVE-2009-2694). NOTE: This issue |
| reportedly exists because of an incomplete fix for CVE-2009-1376 (GLSA |
| 200905-07).</li> |
| <li>bugdave reported that protocols/jabber/auth.c in |
| libpurple as used in Pidgin does not follow the "require TSL/SSL" |
| preference when connecting to older Jabber servers that do not follow |
| the XMPP specification, resulting in a connection to the server without |
| the expected encryption (CVE-2009-3026).</li> |
| </ul> |
| </description> |
| <impact type="high"> |
| <p> |
| A remote attacker could send specially crafted SLP (via MSN) or ICQ web |
| messages, possibly leading to execution of arbitrary code with the |
| privileges of the user running Pidgin, unauthorized information |
| disclosure, or a Denial of Service. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All Pidgin users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=net-im/pidgin-2.5.9-r1"</code> |
| </resolution> |
