RedHat: RHSA-2009-0057:01 Important: squirrelmail security update
Summary
SquirrelMail is an easy-to-configure, standards-based, webmail package
written in PHP. It includes built-in PHP support for the IMAP and SMTP
protocols, and pure HTML 4.0 page-rendering (with no JavaScript required)
for maximum browser-compatibility, strong MIME support, address books, and
folder manipulation.
The Red Hat SquirrelMail packages provided by the RHSA-2009:0010 advisory
introduced a session handling flaw. Users who logged back into SquirrelMail
without restarting their web browsers were assigned fixed session
identifiers. A remote attacker could make use of that flaw to hijack user
sessions. (CVE-2009-0030)
SquirrelMail users should upgrade to this updated package, which contains a
patch to correct this issue. As well, all users who used affected versions
of SquirrelMail should review their preferences.
Summary
Solution
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
