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 web server uses a version of PHP that is affected by multiple vulnerabilities.
DescriptionAccording to its banner, the remote web server is running a version of PHP 5.4.x prior to 5.4.32. It is, therefore, affected by the following vulnerabilities :
- LibGD contains a NULL pointer dereference flaw in its 'gdImageCreateFromXpm' function in the 'gdxpm.c' file.
By using a specially crafted color mapping, a remote attacker could cause a denial of service.
- The original upstream patch for CVE-2013-7345 did not provide a complete solution. It is, therefore, still possible for a remote attacker to deploy a specially crafted input file to cause excessive resources to be used when trying to detect the file type using awk regular expression rules. This can cause a denial of service. (CVE-2014-3538)
- An integer overflow flaw exists in the 'cdf.c' file. By using a specially crafted CDF file, a remote attacker could cause a denial of service. (CVE-2014-3587)
- There are multiple buffer overflow flaws in the 'dns.c' file related to the 'dns_get_record' and 'dn_expand' functions. By using a specially crafted DNS record, a remote attacker could exploit these to cause a denial of service or execute arbitrary code. (CVE-2014-3597)
- A flaw exists in the 'spl_dllist.c' file that may lead to a use-after-free condition in the SPL component when iterating over an object. An attacker could utilize this to cause a denial of service. (CVE-2014-4670)
- A flaw exists in the 'spl_array.c' file that may lead to a use-after-free condition in the SPL component when handling the modification of objects while sorting. An attacker could utilize this to cause a denial of service. (CVE-2014-4698)
- There exist multiple flaws in the GD component within the 'gd_ctx.c' file where user-supplied input is not properly validated to ensure that pathnames lack %00 sequences. By using specially crafted input, a remote attacker could overwrite arbitrary files.
Note that Nessus has not attempted to exploit these issues, but has instead relied only on the application's self-reported version number.
SolutionUpgrade to PHP version 5.4.32 or later.
