Title
FreeRDP 3.0.0 before 3.32.0 Infinite Loop DoS via Gateway Content-Type
Summary
FreeRDP from 3.0.0 before 3.32.0 contains an infinite loop vulnerability in http_response_recv() that allows malicious gateways to exhaust client CPU via crafted Content-Type headers. Attackers controlling a gateway can return a nonzero Content-Length with a semicolon-containing unrecognized Content-Type, pinning a client thread at full CPU indefinitely.

Summary
HAProxy 3 before 3.4.6 allows a remote unauthenticated attacker to cause a denial of service (persistent worker-thread CPU exhaustion) via an HTTP/1.1 chunked request. Although the H1 multiplexer drains the request before closing the stream, the parser repeatedly re-processes the same bytes without making progress. The affected thread stays busy at 100% CPU after timeouts expire and after the client disconnects, and repeated requests can consume all worker threads until the process is restarted.

Title
FreeRDP 2.3.0 before 3.32.0 Infinite Loop via RD Gateway Chunked Response
Summary
FreeRDP from 2.3.0 before 3.32.0 contains an infinite loop vulnerability in http_chuncked_read that allows malicious RD Gateways to hang clients by sending incomplete chunked responses. Attackers can send a partial chunk-size line or footer followed by a clean TLS shutdown, causing zero-byte reads to loop forever and freeze the client decoder thread.

Title
Gnome-remote-desktop: busy-wait dos in vnc tls i/o handlers (gnutls_e_again / gnutls_e_interrupted)
Summary
A flaw was found in gnome-remote-desktop as shipped in Red Hat Enterprise Linux. In the VNC TLS I/O handlers, retryable GnuTLS results (GNUTLS_E_AGAIN and GNUTLS_E_INTERRUPTED) are handled with an unbounded busy loop instead of yielding to the event loop. A remote attacker who can reach an enabled VNC TLS listener can cause the event-loop thread to spin at high CPU with no forward progress, resulting in denial of service.

Title
Denial of Service vulnerability in SAP NetWeaver Application Server ABAP, ABAP Platform and SAP Web Dispatcher
Summary
SAP NetWeaver Application Server ABAP, ABAP Platform, and SAP Web Dispatcher do not sufficiently handle resource consumption when processing certain requests. An unauthenticated attacker could send specially crafted requests to the affected component, causing excessive resource utilization and service disruption. This results in a high impact on availability. There is no impact on confidentiality and integrity.

Title
FFmpeg through 9.0.2 Infinite Loop via RTSP Redirect Handling in rtsp.c
Summary
FFmpeg through 9.0.2 contains an infinite loop vulnerability in ff_rtsp_connect() in libavformat/rtsp.c that follows RTSP 3xx redirects without any redirect limit. Attackers controlling an RTSP server can answer every request with a 302 redirect to itself or another server, causing endless reconnects that saturate a CPU core.

Title
FFmpeg before 8.1.3 HLS Demuxer Infinite Loop via Self-Referencing Playlist
Summary
FFmpeg before 8.1.3 contains an infinite loop vulnerability in the HLS demuxer that allows remote attackers to cause denial of service because parse_playlist() accepts Master Playlist tags inside Media Playlists. Attackers can trick victims into opening a crafted self-referencing playlist that endlessly adds variants in hls_read_header(), causing unbounded CPU and I/O consumption.

Title
FFmpeg through 9.0.2 DASH Demuxer Infinite Loop via Empty SegmentTemplate Media
Summary
FFmpeg through 9.0.2 contains a denial of service vulnerability in the DASH demuxer that allows attackers to trigger an infinite loop by supplying an empty SegmentTemplate media URL. Attackers can craft an .mpd manifest declaring SegmentTemplate media="" so get_current_fragment() calls av_strireplace() with an empty search string, consuming CPU indefinitely.
