Background ========== PHP is a general-purpose scripting language widely used to develop web-based applications. It can run inside a web server using the mod_php module or the CGI version and also stand-alone in a CLI. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-php/php < 4.4.0-r4 *>= 4.3.11-r4 >= 4.4.0-r4 2 dev-php/mod_php < 4.4.0-r8 *>= 4.3.11-r4 >= 4.4.0-r8 3 dev-php/php-cgi < 4.4.0-r5 *>= 4.3.11-r5 >= 4.4.0-r5 ------------------------------------------------------------------- 3 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== Multiple vulnerabilities have been found and fixed in PHP: * a possible $GLOBALS variable overwrite problem through file upload handling, extract() and import_request_variables() (CVE-2005-3390) * a local Denial of Service through the use of the session.save_path option (CVE-2005-3319) * an issue with trailing slashes in allowed basedirs (CVE-2005-3054) * an issue with calling virtual() on Apache 2, allowing to bypass safe_mode and open_basedir restrictions (CVE-2005-3392) * a problem when a request was terminated due to memory_limit constraints during certain parse_str() calls (CVE-2005-3389) * The curl and gd modules allowed to bypass the safe mode open_basedir restrictions (CVE-2005-3391) * a cross-site scripting (XSS) vulnerability in phpinfo() (CVE-2005-3388) Impact ====== Attackers could leverage these issues to exploit applications that are assumed to be secure through the use of proper register_globals, safe_mode or open_basedir parameters. Remote attackers could also conduct cross-site scripting attacks if a page calling phpinfo() was available. Finally, a local attacker could cause a local Denial of Service using malicious session.save_path options. Workaround ========== There is no known workaround that would solve all issues at this time. Resolution ========== All PHP users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose dev-php/php All mod_php users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose dev-php/mod_php All php-cgi users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose dev-php/php-cgi References ========== [ 1 ] CVE-2005-3054 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3054 [ 2 ] CVE-2005-3319 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3319 [ 3 ] CVE-2005-3388 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3388 [ 4 ] CVE-2005-3389 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3389 [ 5 ] CVE-2005-3390 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3390 [ 6 ] CVE-2005-3391 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3391 [ 7 ] CVE-2005-3392 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3392 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200511-08.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.
