PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server.

Security Fix(es):

  • Archive_Tar: allows an unserialization attack because phar: is blocked but PHAR: is not blocked (CVE-2020-28948)

  • Archive_Tar: improper filename sanitization leads to file overwrites (CVE-2020-28949)

  • Archive_Tar: directory traversal due to inadequate checking of symbolic links (CVE-2020-36193)
