The remote Redhat Enterprise Linux 4 / 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2011:1820 advisory.
pidgin (libpurple): Invalid UTF-8 string handling in OSCAR messages (CVE-2011-4601)
pidgin: Multiple NULL pointer deference flaws by processing certain Jingle stanzas in the XMPP protocol plug-in (CVE-2011-4602)
pidgin: SILC remote crash on channel messages (CVE-2011-4603)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
