RedHat: Moderate: squirrelmail security update RHSA-2005:595-02
Summary
Summary
SquirrelMail is a standards-based webmail package written in PHP4. A bug was found in the way SquirrelMail handled the $_POST variable. If a user is tricked into visiting a malicious URL, the user's SquirrelMail preferences could be read or modified. The Common Vulnerabilities and Exposures project assigned the name CAN-2005-2095 to this issue. Several cross-site scripting bugs were discovered in SquirrelMail. An attacker could inject arbitrary Javascript or HTML content into SquirrelMail pages by tricking a user into visiting a carefully crafted URL, or by sending them a carefully constructed HTML email message. The Common Vulnerabilities and Exposures project assigned the name CAN-2005-1769 to this issue. All users of SquirrelMail should upgrade to this updated package, which contains backported patches that resolve these issues.
