GLSA-200710-02 : PHP: Multiple vulnerabilities
high Nessus Plugin ID 26942
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-200710-02 (PHP: Multiple vulnerabilities)Several vulnerabilities were found in PHP. Mattias Bengtsson and Philip Olausson reported integer overflows in the gdImageCreate() and gdImageCreateTrueColor() functions of the GD library which can cause heap-based buffer overflows (CVE-2007-3996). Gerhard Wagner discovered an integer overflow in the chunk_split() function that can lead to a heap-based buffer overflow (CVE-2007-2872). Its incomplete fix caused incorrect buffer size calculation due to precision loss, also resulting in a possible heap-based buffer overflow (CVE-2007-4661 and CVE-2007-4660). A buffer overflow in the sqlite_decode_binary() of the SQLite extension found by Stefan Esser that was addressed in PHP 5.2.1 was not fixed correctly (CVE-2007-1887).
Stefan Esser discovered an error in the zend_alter_ini_entry() function handling a memory_limit violation (CVE-2007-4659). Stefan Esser also discovered a flaw when handling interruptions with userspace error handlers that can be exploited to read arbitrary heap memory (CVE-2007-1883). Disclosure of sensitive memory can also be triggered due to insufficient boundary checks in the strspn() and strcspn() functions, an issue discovered by Mattias Bengtsson and Philip Olausson (CVE-2007-4657) Stefan Esser reported incorrect validation in the FILTER_VALIDATE_EMAIL filter of the Filter extension allowing arbitrary email header injection (CVE-2007-1900). NOTE: This CVE was referenced, but not fixed in GLSA 200705-19.
Stanislav Malyshev found an error with unknown impact in the money_format() function when processing '%i' and '%n' tokens (CVE-2007-4658). zatanzlatan reported a buffer overflow in the php_openssl_make_REQ() function with unknown impact when providing a manipulated SSL configuration file (CVE-2007-4662). Possible memory corruption when trying to read EXIF data in exif_read_data() and exif_thumbnail() occurred with unknown impact.
Several vulnerabilities that allow bypassing of open_basedir and other restrictions were reported, including the glob() function (CVE-2007-4663), the session_save_path(), ini_set(), and error_log() functions which can allow local command execution (CVE-2007-3378), involving the readfile() function (CVE-2007-3007), via the Session extension (CVE-2007-4652), via the MySQL extension (CVE-2007-3997) and in the dl() function which allows loading extensions outside of the specified directory (CVE-2007-4825).
Multiple Denial of Service vulnerabilities were discovered, including a long 'library' parameter in the dl() function (CVE-2007-4887), in several iconv and xmlrpc functions (CVE-2007-4840 and CVE-2007-4783), in the setlocale() function (CVE-2007-4784), in the glob() and fnmatch() function (CVE-2007-4782 and CVE-2007-3806), a floating point exception in the wordwrap() function (CVE-2007-3998), a stack exhaustion via deeply nested arrays (CVE-2007-4670), an infinite loop caused by a specially crafted PNG image in the png_read_info() function of libpng (CVE-2007-2756) and several issues related to array conversion.
Impact :
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.
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-5.2.4_p20070914-r2'
