SynopsisThe remote Debian host is missing a security update.
DescriptionSeveral 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-2016-10397 Incorrect handling of various URI components in the URL parser could be used by attackers to bypass hostname-specific URL checks.
CVE-2017-11143 An invalid free in the WDDX deserialization of boolean parameters could be used by attackers able to inject XML for deserialization to crash the PHP interpreter.
CVE-2017-11144 The openssl extension PEM sealing code did not check the return value of the OpenSSL sealing function, which could lead to a crash of the PHP interpreter.
CVE-2017-11145 Lack of a bounds check in the date extension's timelib_meridian parsing code could be used by attackers able to supply date strings to leak information from the interpreter.
CVE-2017-11147 The PHAR archive handler could be used by attackers supplying malicious archive files to crash the PHP interpreter or potentially disclose information due to a buffer over-read in the phar_parse_pharfile function in ext/phar/phar.c.
For Debian 7 'Wheezy', these problems have been fixed in version 5.4.45-0+deb7u9.
We recommend that you upgrade your php5 packages.
