Vulnerability Assessment Details
PHP: Multiple vulnerabilities
Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200605-08
(PHP: Multiple vulnerabilities)
Several vulnerabilities were discovered on PHP4 and PHP5 by
Infigo, Tonu Samuel and Maksymilian Arciemowicz. These included a
buffer overflow in the wordwrap() function, restriction bypasses in the
copy() and tempname() functions, a cross-site scripting issue in the
phpinfo() function, a potential crash in the substr_compare() function
and a memory leak in the non-binary-safe html_entity_decode() function.
Remote attackers might be able to exploit these issues in PHP
applications making use of the affected functions, potentially
resulting in the execution of arbitrary code, Denial of Service,
execution of scripted contents in the context of the affected site,
security bypass or information leak.
There is no known workaround at this point.
All PHP users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/php-5.1.4"
PHP4 users that wish to keep that version line should upgrade
to the latest 4.x version:
# emerge --sync
# emerge --ask --oneshot --verbose =dev-lang/php-4.4.2-r2
Network Security Threat Level: High
