Background ========== PEAR Net_Traceroute is an OS independent wrapper class for executing traceroute calls from PHP. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-php/PEAR-Net_Traceroute < 0.21.2 >=3D 0.21.2 Description =========== Pasquale Imperato reported that the $host parameter to the traceroute() function in Traceroute.php is not properly sanitized before being passed to exec(). Impact ====== A remote attacker could exploit this vulnerability when user input is passed directly to PEAR Net_Traceroute in a PHP script, possibly resulting in the remote execution of arbitrary shell commands with the privileges of the user running the affected PHP script. Workaround ========== Ensure that all data that is passed to the traceroute() function is properly shell escaped (for instance using the escapeshellcmd() function). Resolution ========== All PEAR Net_Traceroute users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=3Ddev-php/PEAR-Net_Traceroute-0.21.2" References ========== [ 1 ] CVE-2009-4025 http://cve.mitre.org/cgi-bin/cvename.cgi?name=3DCVE-2009-4025 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200911-06.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.
