Package : php5
Version : 5.4.45-0+deb7u14
CVE ID : CVE-2018-10545 CVE-2018-10547 CVE-2018-10548
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.
