CVE-2019-11046

This can read to disclosure of the content of some memory locations.

MEDIUM 5.3EPSS 4.12%

Does this matter?

Lower severity and a low EPSS score (4.12%). Track it; it rarely justifies an emergency change on its own.

Description

In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP bcmath extension functions on some systems, including Windows, can be tricked into reading beyond the allocated space by supplying it with string containing characters that are identified as numeric by the OS but aren't ASCII numbers. This can read to disclosure of the content of some memory locations.
