Affected Packages:

php5

Vulnerable:

Security database references:

In Mitre's CVE dictionary: CVE-2018-10545, CVE-2018-10547, CVE-2018-10548.

More information:

Several issues have been discovered in PHP (recursive acronym for PHP: Hypertext Preprocessor), a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML.

• CVE-2018-10545

  Dumpable FPM child processes allow bypassing opcache access controls because fpm_unix.c makes a PR_SET_DUMPABLE prctl call, allowing one user (in a multiuser environment) to obtain sensitive information from the process memory of a second user's PHP applications by running gcore on the PID of the PHP-FPM worker process.

• CVE-2018-10547

  There is a reflected XSS on the PHAR 403 and 404 error pages via request data of a request for a .phar file. NOTE: this vulnerability exists because of an incomplete fix for CVE-2018-5712.

• CVE-2018-10548

  ext/ldap/ldap.c allows remote LDAP servers to cause a denial of service (NULL pointer dereference and application crash) because of mishandling of the ldap_get_dn return value.

For Debian 7 Wheezy, these problems have been fixed in version 5.4.45-0+deb7u14.

We recommend that you upgrade your php5 packages.
