The code in question exists even in the 0.5.4, so, while it is questionable if such an old version can be attacked with the original exploit, I think that 0.5.4 has this vulnerability too. Have no direct evidence though. >How-To-Repeat: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5101 http://secunia.com/advisories/32651 >Fix: The following VuXML entry should be evaluated and added: --- vuln.xml begins here --- <vuln vid=""> <topic>optipng -- arbitrary code execution via crafted BMP image</topic> <affects> <package> <name>optipng</name> <range><lt>1.6.2</lt></range> </package> </affects> <description> <body xmlns="http://www.w3.org/1999/xhtml">; <p>Secunia reports:</p> <blockquote cite="http://secunia.com/advisories/32651">; <p>A vulnerability has been reported in OptiPNG, which potentially can be exploited by malicious people to compromise a user's system.</p> <p>The vulnerability is caused due to a boundary error in the BMP reader and can be exploited to cause a buffer overflow by tricking a user into processing a specially crafted file.</p> <p>Successful exploitation may allow execution of arbitrary code.</p> <p>The vulnerability is reported in versions prior to 0.6.2.</p> </blockquote> </body> </description> <references> <cvename>CVE-2008-5101</cvename> <url>http://secunia.com/advisories/32651</url>; <url>http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=505399</url>; <url>http://optipng.sourceforge.net/</url>; </references> <dates> <discovery>2008-11-11</discovery> </dates> </vuln> --- vuln.xml ends here --- Please, note that there is PR ports/128877 that updates port to 0.6.2 and this version isn't vulnerable.
