Gentoo Linux Security Advisory

Title: Pidgin: Multiple vulnerabilities (GLSA 200905-07)
Severity: normal
Exploitable: remote
Date: May 25, 2009
Bug(s): #270811
ID: 200905-07

Synopsis


Multiple vulnerabilities in Pidgin might allow for the remote execution of
arbitrary code or a Denial of Service.


Background


Pidgin (formerly Gaim) is an instant messaging client for a variety of
instant messaging protocols.


Affected Packages

Package: net-im/pidgin
Vulnerable: < 2.5.6
Unaffected: >= 2.5.6
Architectures: All supported architectures


Description


Multiple vulnerabilities have been discovered in Pidgin:

• Veracode reported a boundary error in the "XMPP SOCKS5 bytestream
  server" when initiating an outgoing file transfer (CVE-2009-1373).
• Ka-Hing Cheung reported a heap corruption flaw in the QQ protocol
  handler (CVE-2009-1374).
• A memory corruption flaw in
  "PurpleCircBuffer" was disclosed by Josef Andrysek
  (CVE-2009-1375).
• The previous fix for CVE-2008-2927 contains a
  cast from uint64 to size_t, possibly leading to an integer overflow
  (CVE-2009-1376, GLSA 200901-13).

Impact


A remote attacker could send specially crafted messages or files using
the MSN, XMPP or QQ protocols, possibly resulting in the execution of
arbitrary code with the privileges of the user running the application,
or a Denial of Service. NOTE: Successful exploitation might require the
victim's interaction.


Workaround


There is no known workaround at this time.


Resolution


All Pidgin users should upgrade to the latest version:
