Description

In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0 on Windows, PHP link() function accepts filenames with embedded \0 byte and treats them as terminating at that byte. This could lead to security vulnerabilities, e.g. in applications checking paths that the code is allowed to access.

Affected configurations

• php php (>= 7.2.0 <= 7.2.26) • php php (>= 7.3.0 <= 7.3.13) • php php 7.4.0 • tenable security center (< 5.19.0) • fedoraproject fedora 30 • fedoraproject fedora 31
