PHP 5.6.9 Denial Of Service Overflow Vulnerability
8 Nov. 2016
Multiple integer overflows in mcrypt.c in the mcrypt extension in PHP before 5.5.37, 5.6.x before 5.6.23, and 7.x before 7.0.8 allow remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted length value, related to the (1) mcrypt_generic and (2) mdecrypt_generic functions.
Multiple potential remote and local vulnerabilities impacting Perl and PHP have been addressed by HPE NonStop Servers OSS Script Languages. The vulnerabilities include Perl's opportunistic loading of optional modules which might allow local users to gain elevation of privilege via a Trojan horse library under the current working directory.
