RHSA-2009:1066: Important: squirrelmail security update
First published: Tue May 26 2009(Updated: )
SquirrelMail is a standards-based webmail package written in PHP.<br>A server-side code injection flaw was found in the SquirrelMail<br>"map_yp_alias" function. If SquirrelMail was configured to retrieve a<br>user's IMAP server address from a Network Information Service (NIS) server<br>via the "map_yp_alias" function, an unauthenticated, remote attacker using<br>a specially-crafted username could use this flaw to execute arbitrary code<br>with the privileges of the web server. (CVE-2009-1579)<br>Multiple cross-site scripting (XSS) flaws were found in SquirrelMail. An<br>attacker could construct a carefully crafted URL, which once visited by an <br>unsuspecting user, could cause the user's web browser to execute malicious<br>script in the context of the visited SquirrelMail web page. (CVE-2009-1578)<br>It was discovered that SquirrelMail did not properly sanitize Cascading<br>Style Sheets (CSS) directives used in HTML mail. A remote attacker could<br>send a specially-crafted email that could place mail content above<br>SquirrelMail's controls, possibly allowing phishing and cross-site<br>scripting attacks. (CVE-2009-1581)<br>Users of squirrelmail should upgrade to this updated package, which<br>contains backported patches to correct these issues.
