Description:
Tavis Ormandy has reported a vulnerability in ProZilla, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error in the handling of ftp search results in the "get_string_ahref()" function of "ftpsearch.c". This can be exploited to cause a stack-based buffer overflow and allows arbitrary code execution via a malicious server that returns a search result with a specially crafted string in the "HREF" attribute of the "<A>" tag.
Successful exploitation requires that ProZilla is used with the "-ftpsearch" option, and also requires that the attacker is able to poison the DNS cache.
The vulnerability has been reported in version 1.3.7.4. Prior versions may also be affected.
