The remote Solaris system is missing necessary patches to address security updates :

  - The Yahoo! protocol plugin in libpurple in Pidgin before     2.10.8 does not properly validate UTF-8 data, which     allows remote attackers to cause a denial of service     (application crash) via crafted byte sequences.
    (CVE-2012-6152)

  - The MXit protocol plugin in libpurple in Pidgin before     2.10.7 might allow remote attackers to create or     overwrite files via a crafted (1) mxit or (2)     mxit/imagestrips pathname. (CVE-2013-0271)

  - Buffer overflow in http.c in the MXit protocol plugin in     libpurple in Pidgin before 2.10.7 allows remote servers     to execute arbitrary code via a long HTTP header.
    (CVE-2013-0272)

  - sametime.c in the Sametime protocol plugin in libpurple     in Pidgin before 2.10.7 does not properly terminate long     user IDs, which allows remote servers to cause a denial     of service (application crash) via a crafted packet.
    (CVE-2013-0273)

  - 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. (CVE-2013-0274)

  - Multiple integer signedness errors in libpurple in     Pidgin before 2.10.8 allow remote attackers to cause a     denial of service (application crash) via a crafted     timestamp value in an XMPP message. (CVE-2013-6477)

  - 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. (CVE-2013-6478)

  - 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.
    (CVE-2013-6479)

  - 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.
    (CVE-2013-6481)

  - Pidgin before 2.10.8 allows remote MSN servers to cause     a denial of service (NULL pointer dereference and crash)     via a crafted (1) SOAP response, (2) OIM XML response,     or (3) Content-Length header. (CVE-2013-6482)

  - The XMPP protocol plugin in libpurple in Pidgin before     2.10.8 does not properly determine whether the from     address in an iq reply is consistent with the to address     in an iq request, which allows remote attackers to spoof     iq traffic or cause a denial of service (NULL pointer     dereference and application crash) via a crafted reply.
    (CVE-2013-6483)

  - The STUN protocol implementation in libpurple in Pidgin     before 2.10.8 allows remote STUN servers to cause a     denial of service (out-of-bounds write operation and     application crash) by triggering a socket read error.
    (CVE-2013-6484)

  - Buffer overflow in util.c in libpurple in Pidgin before     2.10.8 allows remote HTTP servers to cause a denial of     service (application crash) or possibly have unspecified     other impact via an invalid chunk-size field in chunked     transfer-coding data. (CVE-2013-6485)

  - gtkutils.c in Pidgin before 2.10.8 on Windows allows     user-assisted remote attackers to execute arbitrary     programs via a message containing a file: URL that is     improperly handled during construction of an     explorer.exe command. NOTE: this vulnerability exists     because of an incomplete fix for CVE-2011-3185.
    (CVE-2013-6486)

  - Integer overflow in libpurple/protocols/gg/lib/http.c in     the Gadu-Gadu (gg) parser in Pidgin before 2.10.8 allows     remote attackers to have an unspecified impact via a     large Content-Length value, which triggers a buffer     overflow. (CVE-2013-6487)

  - Integer signedness error in the MXit functionality in     Pidgin before 2.10.8 allows remote attackers to cause a     denial of service (segmentation fault) via a crafted     emoticon value, which triggers an integer overflow and a     buffer overflow. (CVE-2013-6489)

  - The SIMPLE protocol functionality in Pidgin before     2.10.8 allows remote attackers to have an unspecified     impact via a negative Content-Length header, which     triggers a buffer overflow. (CVE-2013-6490)

  - 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.
    (CVE-2014-0020)

The remote Redhat Enterprise Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2014:0139 advisory.

    Pidgin is an instant messaging program which can log in to multiple     accounts on multiple instant messaging networks simultaneously.

    A heap-based buffer overflow flaw was found in the way Pidgin processed     certain HTTP responses. A malicious server could send a specially crafted     HTTP response, causing Pidgin to crash or potentially execute arbitrary     code with the permissions of the user running Pidgin. (CVE-2013-6485)

    Multiple heap-based buffer overflow flaws were found in several protocol     plug-ins in Pidgin (Gadu-Gadu, MXit, SIMPLE). A malicious server could send     a specially crafted message, causing Pidgin to crash or potentially execute     arbitrary code with the permissions of the user running Pidgin.
    (CVE-2013-6487, CVE-2013-6489, CVE-2013-6490)

    Multiple denial of service flaws were found in several protocol plug-ins in     Pidgin (Yahoo!, XMPP, MSN, stun, IRC). A remote attacker could use these     flaws to crash Pidgin by sending a specially crafted message.
    (CVE-2012-6152, CVE-2013-6477, CVE-2013-6481, CVE-2013-6482, CVE-2013-6484,     CVE-2014-0020)

    It was found that the Pidgin XMPP protocol plug-in did not verify the     origin of iq replies. A remote attacker could use this flaw to spoof an     iq reply, which could lead to injection of fake data or cause Pidgin to     crash via a NULL pointer dereference. (CVE-2013-6483)

    A flaw was found in the way Pidgin parsed certain HTTP response headers.
    A remote attacker could use this flaw to crash Pidgin via a specially     crafted HTTP response header. (CVE-2013-6479)

    It was found that Pidgin crashed when a mouse pointer was hovered over a     long URL. A remote attacker could use this flaw to crash Pidgin by sending     a message containing a long URL string. (CVE-2013-6478)

    Red Hat would like to thank the Pidgin project for reporting these issues.
    Upstream acknowledges Thijs Alkemade, Robert Vehse, Jaime Breva Ribes,     Jacob Appelbaum of the Tor Project, Daniel Atallah, Fabian Yamaguchi and     Christian Wressnegger of the University of Goettingen, Matt Jones of     Volvent, and Yves Younan, Ryan Pentney, and Pawel Janic of Sourcefire VRT     as the original reporters of these issues.

    All pidgin users are advised to upgrade to these updated packages, which     contain backported patches to correct these issues. Pidgin must be     restarted for this update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
