USN10-1 : XML library vulnerabilities |
||
XML library vulnerabilities Detailed Explanation for this Vulnerability Assessment Summary : These remote packages are missing security patches : - libxml2 - libxml2-dev - libxml2-doc - libxml2-python2.3 - libxml2-utils Description : Several buffer overflows have been discovered in libxml2's FTP connection and DNS resolution functions. Supplying very long FTP URLs or IP addresses might result in execution of arbitrary code with the rights of the process using libxml2. Since libxml2 is used in packages like php4-imagick, the vulnerability also might lead to privilege escalation, like executing attacker supplied code with a web server's rights. However, this does not affect the core XML parsing code, which is what the majority of programs use this library for. Solution : Upgrade to : - libxml2-2.6.11-3ubuntu1.1 (Ubuntu 4.10) - libxml2-dev-2.6.11-3ubuntu1.1 (Ubuntu 4.10) - libxml2-doc-2.6.11-3ubuntu1.1 (Ubuntu 4.10) - libxml2-python2.3-2.6.11-3ubuntu1.1 (Ubuntu 4.10) - libxml2-utils-2.6.11-3ubuntu1.1 (Ubuntu 4.10) Network Security Threat Level: High Networks Security ID: Vulnerability Assessment Copyright: Ubuntu Security Notice (C) 2005 Canonical, Inc. / NASL script (C) 2005 Michel Arboi |
