|Gentoo Linux Security Advisory
Title: PEAR Net_Traceroute: Command injection (GLSA 200911-06)
Date: November 26, 2009
An input sanitation error in PEAR Net_Traceroute might allow remote
attackers to execute arbitrary commands.
PEAR Net_Traceroute is an OS independent wrapper class for executing
traceroute calls from PHP.
Vulnerable: < 0.21.2
Unaffected: >= 0.21.2
Architectures: All supported architectures
Pasquale Imperato reported that the $host parameter to the traceroute()
function in Traceroute.php is not properly sanitized before being
passed to exec().
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.
Ensure that all data that is passed to the traceroute() function is
properly shell escaped (for instance using the escapeshellcmd()
All PEAR Net_Traceroute users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-php/PEAR-Net_Traceroute-0.21.2"
