CentOS Errata and Security Advisory CESA-2009:0457
libwmf is a library for reading and converting Windows Metafile Format (WMF) vector graphics. libwmf is used by applications such as GIMP and ImageMagick.
A pointer use-after-free flaw was found in the GD graphics library embedded in libwmf. An attacker could create a specially-crafted WMF file that would cause an application using libwmf to crash or, potentially, execute arbitrary code as the user running the application when opened by a victim. (CVE-2009-1364)
Note: This flaw is specific to the GD graphics library embedded in libwmf. It does not affect the GD graphics library from the "gd" packages, or applications using it.
Red Hat would like to thank Tavis Ormandy of the Google Security Team for responsibly reporting this flaw.
All users of libwmf are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the update, all applications using libwmf must be restarted for the update to take effect.
