[***** Start Red Hat RHSA-2006:0597-5 *****] Moderate: libwmf security update Advisory: RHSA-2006:0597-5 Type: Security Advisory Issued on: 2006-07-18 Last updated on: 2006-07-18 Affected Products: Red Hat Desktop (v. 4) Red Hat Enterprise Linux AS (v. 4) Red Hat Enterprise Linux ES (v. 4) Red Hat Enterprise Linux WS (v. 4) CVEs (cve.mitre.org): CVE-2006-3376 Details Updated libwmf packages that fix a security flaw are now available for Red Hat Enterprise Linux 4. This update has been rated as having moderate security impact by the Red Hat Security Response Team. Libwmf is a library for reading and converting Windows MetaFile vector graphics (WMF). Libwmf is used by packages such as The GIMP and ImageMagick. An integer overflow flaw was discovered in libwmf. An attacker could create a carefully crafted WMF flaw that could execute arbitrary code if opened by a victim. (CVE-2006-3376). Users of libwmf should update to these packages which contain a backported security patch to correct this issue. Solution Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system.
