Background ========== GD is a graphic library for fast image creation. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/gd < 2.0.35 >= 2.0.35 Description =========== Xavier Roche discovered an infinite loop in the gdPngReadData() function when processing a truncated PNG file (CVE-2007-2756). An integer overflow has been discovered in the gdImageCreateTrueColor() function (CVE-2007-3472). An error has been discovered in the function gdImageCreateXbm() function (CVE-2007-3473). Unspecified vulnerabilities have been discovered in the GIF reader (CVE-2007-3474). An error has been discovered when processing a GIF image that has no global color map (CVE-2007-3475). An array index error has been discovered in the file gd_gif_in.c when processing images with an invalid color index (CVE-2007-3476). An error has been discovered in the imagearc() and imagefilledarc() functions when processing overly large angle values (CVE-2007-3477). A race condition has been discovered in the gdImageStringFTEx() function (CVE-2007-3478). Impact ====== A remote attacker could exploit one of these vulnerabilities to cause a Denial of Service or possibly execute arbitrary code with the privileges of the user running GD. Workaround ========== There is no known workaround at this time. Resolution ========== All GD users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/gd-2.0.35" References ========== [ 1 ] CVE-2007-2756 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-2756 [ 2 ] CVE-2007-3472 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3472 [ 3 ] CVE-2007-3473 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3473 [ 4 ] CVE-2007-3474 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3474 [ 5 ] CVE-2007-3475 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3475 [ 6 ] CVE-2007-3476 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3476 [ 7 ] CVE-2007-3477 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3477 [ 8 ] CVE-2007-3478 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3478 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200708-05.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
