New Qt packages are available for Slackware 9.0, 9.1, 10.0, and -current to fix security issues. Bugs in the routines that handle PNG, BMP, GIF, and JPEG images may allow an attacker to cause unauthorized code to execute when a specially crafted image file is processed. These flaws may also cause crashes that lead to a denial of service. More details about these issues may be found in the Common Vulnerabilities and Exposures (CVE) database: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2004-0691 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2004-0692 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2004-0693
