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.
VPR Score: 5.9
SynopsisThe remote Oracle Linux host is missing one or more security updates.
DescriptionFrom Red Hat Security Advisory 2014:1327 :
Updated php packages that fix multiple security issues are now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server. PHP's fileinfo module provides functions used to identify a particular file according to the type of data contained by the file.
A buffer overflow flaw was found in the way the File Information (fileinfo) extension processed certain Pascal strings. A remote attacker able to make a PHP application using fileinfo convert a specially crafted Pascal string provided by an image file could cause that application to crash. (CVE-2014-3478)
Multiple flaws were found in the File Information (fileinfo) extension regular expression rules for detecting various files. A remote attacker could use either of these flaws to cause a PHP application using fileinfo to consume an excessive amount of CPU. (CVE-2014-3538)
It was found that the fix for CVE-2012-1571 was incomplete; the File Information (fileinfo) extension did not correctly parse certain Composite Document Format (CDF) files. A remote attacker could use this flaw to crash a PHP application using fileinfo via a specially crafted CDF file. (CVE-2014-3587)
It was found that PHP's gd extension did not properly handle file names with a null character. A remote attacker could possibly use this flaw to make a PHP application access unexpected files and bypass intended file system access restrictions. (CVE-2014-5120)
A NULL pointer dereference flaw was found in the gdImageCreateFromXpm() function of PHP's gd extension. A remote attacker could use this flaw to crash a PHP application using gd via a specially crafted X PixMap (XPM) file. (CVE-2014-2497)
Multiple buffer over-read flaws were found in the php_parserr() function of PHP. A malicious DNS server or a man-in-the-middle attacker could possibly use this flaw to execute arbitrary code as the PHP interpreter if a PHP application used the dns_get_record() function to perform a DNS query. (CVE-2014-3597)
Two use-after-free flaws were found in the way PHP handled certain Standard PHP Library (SPL) Iterators and ArrayIterators. A malicious script author could possibly use either of these flaws to disclose certain portions of server memory. (CVE-2014-4670, CVE-2014-4698)
The CVE-2014-3478 issue was discovered by Francisco Alonso of Red Hat Product Security, the CVE-2014-3538 issue was discovered by Jan Kaluza of the Red Hat Web Stack Team, and the CVE-2014-3597 issue was discovered by David Kutalek of the Red Hat BaseOS QE.
All php users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the httpd daemon must be restarted for the update to take effect.
