3. Description:

 

SquirrelMail is a standards-based webmail package written in PHP.

 

A server-side code injection flaw was found in the SquirrelMail

"map_yp_alias" function. If SquirrelMail was configured to retrieve a

user's IMAP server address from a Network Information Service (NIS) server

via the "map_yp_alias" function, an unauthenticated, remote attacker using

a specially-crafted username could use this flaw to execute arbitrary code

with the privileges of the web server. (CVE-2009-1579)

 

Multiple cross-site scripting (XSS) flaws were found in SquirrelMail. An

attacker could construct a carefully crafted URL, which once visited by an

unsuspecting user, could cause the user's web browser to execute malicious

script in the context of the visited SquirrelMail web page. (CVE-2009-1578)

 

It was discovered that SquirrelMail did not properly sanitize Cascading

Style Sheets (CSS) directives used in HTML mail. A remote attacker could

send a specially-crafted email that could place mail content above

SquirrelMail's controls, possibly allowing phishing and cross-site

scripting attacks. (CVE-2009-1581)

 

Users of squirrelmail should upgrade to this updated package, which

contains backported patches to correct these issues.
