GLSA-200811-05 : PHP: Multiple vulnerabilities
critical Nessus Plugin ID 34787
Synopsis
The remote Gentoo host is missing one or more security-related patches.Description
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.
Solution
All PHP users should upgrade to the latest version:# emerge --sync # emerge --ask --oneshot --verbose '>=dev-lang/php-5.2.6-r6'
