CVE Descriptions

PHP 5.2.5 and earlier allows context-dependent attackers to cause a denial of service (application crash) via a long string in (1) the domain parameter to the dgettext function, the message parameter to the (2) dcgettext or (3) gettext function, the msgid1 parameter to the (4) dngettext or (5) ngettext function, or (6) the classname parameter to the stream_wrapper_register function. NOTE: this might not be a vulnerability in most web server environments that support multiple threads, unless this issue can be demonstrated for code execution.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

source: https://www.securityfocus.com/bid/26428/info PHP is prone to multiple denial-of-service vulnerabilities because it fails to perform adequate boundary checks on user-supplied input. Attackers can exploit these issues to cause denial-of-service conditions. Given the nature of these issues, attackers may also be able to execute arbitrary code, but this has not been confirmed. PHP 5.2.5 is vulnerable; other versions may also be affected.
