php4 vulnerabilities Detailed Explanation for this Vulnerability Assessment Summary : These remote packages are missing security patches : - libapache2-mod-php4 - php4 - php4-cgi - php4-curl - php4-dev - php4-domxml - php4-gd - php4-ldap - php4-mcal - php4-mhash - php4-mysql - php4-odbc - php4-pear - php4-recode - php4-snmp - php4-sybase - php4-xslt Description : Stefan Esser reported several buffer overflows in PHP's variable unserializing handling. These could permit a possible hacker to execute arbitrary code on the server with the PHP interpreter's rights by sending specially crafted input strings (form data, cookie values, and similar). Additionally, Ilia Alshanetsky discovered a buffer overflow in the exif_read_data() function. Attackers could execute arbitrary code on the server by sending a JPEG image with a very long "sectionname" value to PHP applications that support image uploads. Solution : Upgrade to : - libapache2-mod-php4-4.3.8-3ubuntu7.1 (Ubuntu 4.10) - php4-4.3.8-3ubuntu7.1 (Ubuntu 4.10) - php4-cgi-4.3.8-3ubuntu7.1 (Ubuntu 4.10) - php4-curl-4.3.8-3ubuntu7.1 (Ubuntu 4.10) - php4-dev-4.3.8-3ubuntu7.1 (Ubuntu 4.10) - php4-domxml-4.3.8-3ubuntu7.1 (Ubuntu 4.10) - php4-gd-4.3.8-3ubuntu7.1 (Ubuntu 4.10) - php4-ldap-4.3.8-3ubuntu7.1 (Ubuntu 4.10) - php4-mcal-4.3.8-3ubuntu7.1 (Ubuntu 4.10) - php4-mhash-4.3.8-3ubuntu7.1 (Ubuntu 4.10) - php4-mysql-4.3.8-3ubuntu7.1 (Ubuntu 4.10) - php4-odbc-4.3.8-3 [...] Network Security Threat Level: High Networks Security ID: Vulnerability Assessment Copyright: Ubuntu Security Notice (C) 2005 Canonical, Inc. / NASL script (C) 2005 Michel Arboi |
