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 Red Hat host is missing one or more security updates.
DescriptionUpdated php53 and php packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5 and 6 respectively.
The Red Hat Security Response Team 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.
Multiple denial of service flaws were found in the way the File Information (fileinfo) extension parsed certain Composite Document Format (CDF) files. A remote attacker could use either of these flaws to crash a PHP application using fileinfo via a specially crafted CDF file. (CVE-2014-0237, CVE-2014-0238, CVE-2014-3479, CVE-2014-3480, CVE-2012-1571)
Two denial of service flaws were found in the way the File Information (fileinfo) extension handled indirect and search rules. A remote attacker could use either of these flaws to cause a PHP application using fileinfo to crash or consume an excessive amount of CPU.
A heap-based buffer overflow flaw was found in the way PHP parsed DNS TXT records. 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-2014-4049)
A type confusion issue was found in PHP's phpinfo() function. A malicious script author could possibly use this flaw to disclose certain portions of server memory. (CVE-2014-4721)
A buffer over-read flaw was found in the way the DateInterval class parsed interval specifications. An attacker able to make a PHP application parse a specially crafted specification using DateInterval could possibly cause the PHP interpreter to crash. (CVE-2013-6712)
A type confusion issue was found in the SPL ArrayObject and SPLObjectStorage classes' unserialize() method. A remote attacker able to submit specially crafted input to a PHP application, which would then unserialize this input using one of the aforementioned methods, could use this flaw to execute arbitrary code with the privileges of the user running that PHP application. (CVE-2014-3515)
The CVE-2014-0237, CVE-2014-0238, CVE-2014-3479, and CVE-2014-3480 issues were discovered by Francisco Alonso of Red Hat Product Security.
All php53 and php users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
SolutionUpdate the affected packages.
