DESCRIPTION:
tzitaroth has reported a vulnerability in Gregarius, which can be
exploited by malicious people to conduct cross-site scripting and SQL
injection attacks.

1) Input passed to the "rss_query" parameter in search.php and to the
"tag" parameter in tags.php isn't properly sanitised before being
returned to the user. This can be exploited to execute arbitrary HTML
and script code in a user's browser session in context of an affected
site.

2) Input passed to the "folder" parameter in feed.php isn't properly
sanitised before being used in a SQL query. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

The vulnerabilities have been confirmed in version 0.5.2. Prior
versions may also be affected.

SOLUTION:
The vulnerabilities have reportedly been fixed in the CVS
repositories.
