Critical: firefox security update
Type/Severity
Security Advisory: Critical
Topic
Updated firefox packages that fix two security issues are now available for
Red Hat Enterprise Linux 4 and 5.
This update has been rated as having critical security impact by the Red
Hat Security Response Team.
Description
Mozilla Firefox is an open source Web browser. XULRunner provides the XUL
Runtime environment for Mozilla Firefox.
A memory corruption flaw was discovered in the way Firefox handles XML
files containing an XSLT transform. A remote attacker could use this flaw
to crash Firefox or, potentially, execute arbitrary code as the user
running Firefox. (CVE-2009-1169)
A flaw was discovered in the way Firefox handles certain XUL garbage
collection events. A remote attacker could use this flaw to crash Firefox
or, potentially, execute arbitrary code as the user running Firefox.
(CVE-2009-1044)
For technical details regarding these flaws, refer to the Mozilla security
advisories. You can find a link to the Mozilla advisories in the References
section of this errata.
Firefox users should upgrade to these updated packages, which resolve these
issues. For Red Hat Enterprise Linux 4, they contain backported patches to
the firefox package. For Red Hat Enterprise Linux 5, they contain
backported patches to the xulrunner packages. After installing the update,
Firefox must be restarted for the changes to take effect.
