New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200811-05 (PHP: Multiple vulnerabilities)

Several vulnerabilitites were found in PHP:
PHP ships a vulnerable version of the PCRE library which allows for the circumvention of security restrictions or even for remote code execution in case of an application which accepts user-supplied regular expressions (CVE-2008-0674).
Multiple crash issues in several PHP functions have been discovered.
Ryan Permeh reported that the init_request_info() function in sapi/cgi/cgi_main.c does not properly consider operator precedence when calculating the length of PATH_TRANSLATED (CVE-2008-0599).
An off-by-one error in the metaphone() function may lead to memory corruption.
Maksymilian Arciemowicz of SecurityReason Research reported an integer overflow, which is triggerable using printf() and related functions (CVE-2008-1384).
Andrei Nigmatulin reported a stack-based buffer overflow in the FastCGI SAPI, which has unknown attack vectors (CVE-2008-2050).
Stefan Esser reported that PHP does not correctly handle multibyte characters inside the escapeshellcmd() function, which is used to sanitize user input before its usage in shell commands (CVE-2008-2051).
Stefan Esser reported that a short-coming in PHP's algorithm of seeding the random number generator might allow for predictible random numbers (CVE-2008-2107, CVE-2008-2108).
The IMAP extension in PHP uses obsolete c-client API calls making it vulnerable to buffer overflows as no bounds checking can be done (CVE-2008-2829).
Tavis Ormandy reported a heap-based buffer overflow in pcre_compile.c in the PCRE version shipped by PHP when processing user-supplied regular expressions (CVE-2008-2371).
CzechSec reported that specially crafted font files can lead to an overflow in the imageloadfont() function in ext/gd/gd.c, which is part of the GD extension (CVE-2008-3658).
Maksymilian Arciemowicz of SecurityReason Research reported that a design error in PHP's stream wrappers allows to circumvent safe_mode checks in several filesystem-related PHP functions (CVE-2008-2665, CVE-2008-2666).
Laurent Gaffie discovered a buffer overflow in the internal memnstr() function, which is used by the PHP function explode() (CVE-2008-3659).
An error in the FastCGI SAPI when processing a request with multiple dots preceding the extension (CVE-2008-3660).
Impact :

These vulnerabilities might allow a remote attacker to execute arbitrary code, to cause a Denial of Service, to circumvent security restrictions, to disclose information, and to manipulate files.
Workaround :

There is no known workaround at this time.


All PHP users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-lang/php-5.2.6-r6'
