Two vulnerabilities have been identified in Lighttpd, which could be exploited by remote attackers to cause a denial of service.
The first issue is caused by an infinite loop error in the "connection_handle_read_state()" [connections.c] function when handling a client connection abort while parsing the "\r\n\r\n" sequence, which could be exploited by remote attackers to crash an affected server or exhaust all available memory resources, creating a denial of service condition.
The second vulnerability is caused by a NULL pointer dereference error in "server.c" when processing a file with a "mtime" of 0, which could be exploited by an attacker who is able to upload a file or manipulate the "mtime" to crash an affected server.
