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 : An integer overflow was discovered in the exif_process_IFD_TAG() function in PHP4's EXIF module. EXIF tags with a specially crafted "Image File Directory" (IFD) tag caused a buffer overflow which could have been exploited to execute arbitrary code with the rights of the PHP4 server. (CVE-2005-1042) The same module also contained a Denial of Service vulnerability. EXIF headers with a large IFD nesting level caused an unbound recursion which would eventually overflow the stack and cause the executed program to crash. (CVE-2005-1043) In web applications that automatically process EXIF tags of uploaded images, both vulnerabilities could be exploited remotely. Solution : Upgrade to : - libapache2-mod-php4-4.3.8-3ubuntu7.8 (Ubuntu 4.10) - php4-4.3.8-3ubuntu7.8 (Ubuntu 4.10) - php4-cgi-4.3.8-3ubuntu7.8 (Ubuntu 4.10) - php4-curl-4.3.8-3ubuntu7.8 (Ubuntu 4.10) - php4-dev-4.3.8-3ubuntu7.8 (Ubuntu 4.10) - php4-domxml-4.3.8-3ubuntu7.8 (Ubuntu 4.10) - php4-gd-4.3.8-3ubuntu7.8 (Ubuntu 4.10) - php4-ldap-4.3.8-3ubuntu7.8 (Ubuntu 4.10) - php4-mcal-4.3.8-3ubuntu7.8 (Ubuntu 4.10) - php4-mhash-4.3.8-3ubuntu7.8 (Ubuntu 4.10) - php4-mysql-4.3.8-3ubuntu7.8 (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 |
