CVE-2019-16200 Information

Description

GNU Serveez through 0.2.2 has an Information Leak. An attacker may send an HTTP POST request to the /cgi-bin/reader URI. The attacker must include a Content-length header with a large positive value that when represented in 32 bit binary evaluates to a negative number. The problem exists in the http_cgi_write function under http-cgi.c; however exploitation might show svz_envblock_add in libserveez/passthrough.c as the location of the heap-based buffer over-read.
