The remote Ubuntu 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5903-1 advisory. It was discovered that lighttpd incorrectly handled certain inputs, which could result in a stack buffer overflow. A remote attacker could...

GLSA-202210-12 : Lighttpd: Denial of Service

The remote host is affected by the vulnerability described in GLSA-202210-12 Lighttpd: Denial of Service - In lighttpd 1.4.65, modwstunnel does not initialize a handler function pointer if an invalid HTTP request websocket handshake is received. It leads to null pointer dereference which crashes...

Denial Of Service (DoS)

lighttpd is vulnerable to denial of service. The vulnerability exists in gwbackend.c where there is a resource leak which will lead to a connection slot exhaustion after a large amount of anomalous TCP behavior causing an application crash...

CVE-2022-41556

A resource leak in gwbackend.c in lighttpd 1.4.56 through 1.4.66 could lead to a denial of service connection-slot exhaustion after a large amount of anomalous TCP behavior by clients. It is related to RDHUP mishandling in certain HTTP/1.1 chunked situations. Use of modfastcgi is, for example,...

T...

CVE-2008-4109

A certain Debian patch for OpenSSH before 4.3p2-9etch3 on etch; before 4.6p1-1 on sid and lenny; and on other distributions such as SUSE uses functions that are not async-signal-safe in the signal handler for login timeouts, which allows remote attackers to cause a denial of service connection sl...

openssh: Prevent connection slot exhaustion attacks

The default configuration of OpenSSH through 6.1 enforces a fixed time limit between establishing a TCP connection and completing a login, which makes it easier for remote attackers to cause a denial of service connection-slot exhaustion by periodically making many new TCP connections...

Directory traversal

Directory Proxy Server DPS in Sun Java System Directory Server Enterprise Edition 6.0 through 6.3.1 does not enable the SOKEEPALIVE socket option, which makes it easier for remote attackers to cause a denial of service connection slot exhaustion via multiple connections, aka Bug Id 6782659...
