Multiple buffer overflows in (1) http.c, (2) http-retr.c, (3) main.c and other code that handles network protocols in ProZilla 1.3.6-r2 and earlier allow remote servers to execute arbitrary code via a long Location header.

Format string vulnerability in ProZilla 1.3.7.3 and earlier allows remote attackers to execute arbitrary code via format string specifiers in the Location header.

Buffer overflow in the get_string_ahref function for ProZilla 1.3.7.4 and possibly earlier, with the -ftpsearch option enabled, allows remote servers to execute arbitrary code via a search response with a crafted string in the HREF field of an <A> tag.
