httpd: httpd: HTTP/2 Remote Denial of Service via compression bomb and Slowloris-style attack

A flaw was found in HTTP/2, affecting various web servers. A remote attacker can exploit this vulnerability by combining an HPACK compression bomb with a zero-byte flow-control window. This technique allows a small amount of data to expand into large memory allocations on the server, which are th...

CVE-2026-45103

A flaw was found in OpenSIPS, a Session Initiation Protocol SIP server. An integer overflow vulnerability exists in the TCP message framing layer when parsing the Content-Length header. An unauthenticated, network-based attacker can exploit this by sending a crafted Content-Length value, causing...

CVE-2026-45100

OpenSIPS is a Session Initiation Protocol SIP server implementation. Versions 3.4.0-beta through 3.6.5 and 4.0.0-beta contain a buffer overflow in the s.b64encode string transformation. The size check for s.b64encode only verifies that the input fits within the 64 KB transformation buffer, but...

CVE-2026-45538

A flaw was found in OpenSIPS, a Session Initiation Protocol SIP server. An unauthenticated remote attacker can exploit a stack buffer overflow by sending a specially crafted SIP message with an overly long header name. This can cause the server to crash, leading to a denial of service. In certain...
