[R1] SecurityCenter 5.3.2, 5.4.0, 5.4.2, 5.4.5, 5.5.0, and 5.5.1 Fixes Multiple Vulnerabilities

Medium

Synopsis

Tenable has released updates for SecurityCenter 5.3.2, 5.4.0, 5.4.2, 5.4.5, 5.5.0, and 5.5.1 to bring the version of PHP included with them to 5.6.31.

PHP 5.6.31 addresses multiple vulnerabilities:

CVE-2017-11142: In PHP before 5.6.31, 7.x before 7.0.17, and 7.1.x before 7.1.3, remote attackers could cause a CPU consumption denial of service attack by injecting long form variables, related to main/php_variables.c.
CVE-2017-11143: In PHP before 5.6.31, 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, related to an invalid free for an empty boolean element in ext/wddx/wddx.c.
CVE-2017-11144: In PHP before 5.6.31, 7.x before 7.0.21, and 7.1.x before 7.1.7, 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, related to an interpretation conflict for a negative number in ext/openssl/openssl.c, and an OpenSSL documentation omission.
CVE-2017-11145: In PHP before 5.6.31, 7.x before 7.0.21, and 7.1.x before 7.1.7, 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, related to an ext/date/lib/parse_date.c out-of-bounds read affecting the php_parse_date function.
CVE-2017-11146: In PHP through 5.6.31, 7.x through 7.0.21, and 7.1.x through 7.1.7, lack of bounds checks 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, related to ext/date/lib/parse_date.c out-of-bounds reads affecting the php_parse_date function. NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-11145.
CVE-2017-11147: In PHP before 5.6.30 and 7.x before 7.0.15, 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.
CVE-2017-7890: PHP 'gd_gif_in.c' Memory Corruption Vulnerability
