Title
FFmpeg through 9.0.2 Assertion Failure DoS via cbs_jpeg_assemble_fragment
Summary
FFmpeg through 9.0.2 contains a denial of service vulnerability in cbs_jpeg_assemble_fragment() that miscounts 0xff stuffing bytes in JPEG scan headers. Attackers can supply a crafted JPEG/MJPEG stream with 0xff in the scan header, triggering an av_assert0 abort when CBS-based bitstream filters process it.

Title
FFmpeg through 9.0.2 Reachable Assertion in libxevd EVC Decoder Wrapper
Summary
FFmpeg through 9.0.2 contains a reachable assertion vulnerability in libxevd_receive_frame() in libavcodec/libxevd.c that returns success when an access unit produces no frame. Attackers can supply a crafted EVC file with truncated or picture-less access units to trigger the av_assert0() on frame->private_ref, aborting any decoding application.

FFmpeg 8.1 through 9.0.2 Denial of Service via DPX Vulkan Hwaccel Error Path
Summary
FFmpeg 8.1 through 9.0.2 contains a denial of service vulnerability in libavcodec/dpx.c that leaves dpx->hwaccel_picture_private allocated when Vulkan hwaccel callbacks fail. Attackers can supply crafted DPX images that make start_frame, decode_slice or end_frame fail, triggering an av_assert0 abort on the next frame and terminating the decoding application.

Title
FFmpeg 8.1 through 9.0.2 Denial of Service via lcevc_metadata Bitstream Filter
Summary
FFmpeg 8.1 through 9.0.2 contains a denial of service vulnerability in the lcevc_metadata bitstream filter caused by a process block position mismatch in lcevc_metadata_handle_vui(). Attackers can supply crafted LCEVC access units with two IDR or non-IDR NAL units to trigger an av_assert0 failure in ff_cbs_lcevc_list_add(), aborting the application.

Title
FFmpeg through 9.0.2 TTA Encoder Reachable Assertion via tta_encode_frame()
Summary
FFmpeg through 9.0.2 contains a reachable assertion vulnerability in the TTA encoder's tta_encode_frame() in libavcodec/ttaenc.c, which never reserves output packet space for the 4-byte CRC. Attackers can supply audio whose sample values and length produce a small, poorly compressible final frame, triggering the av_assert0() in flush_put_bits() and aborting applications transcoding to TTA.

Trendyol kafka-konsumer 2.3.3 before 2.6.18 Denial of Service via Batch Consumer Panic
Summary
Trendyol kafka-konsumer from 2.3.3 before 2.6.18 contains a denial of service vulnerability in batch_consumer.go that panics when a single record exceeds MessageGroupByteSizeLimit. Attackers able to produce to the consumed topic can publish one oversized record that terminates the consumer before offset commit, causing a persistent crash loop.

Zebra zebrad before 7.0.0 Reachable Assertion DoS via Peer Disconnection
Summary
ZcashFoundation Zebra zebrad before 7.0.0 contains a reachable assertion race condition that allows unauthenticated remote peers to abort the node by triggering disconnection during a blocked outbound send. Malicious peers can return empty FindBlocks or FindHeaders replies and stop reading their socket, dropping an unresolved MustUseClientResponseSender and terminating syncing nodes.

Title
FreeRDP before 3.32.2 Unauthenticated Denial of Service via CredSSP TSRequest
Summary
FreeRDP before 3.32.2 contains a denial of service vulnerability in the NLA-enabled shadow server when a CredSSP TSRequest omits negoTokens. Unauthenticated attackers can send a crafted seven-byte TSRequest containing only the version field to trigger a fatal WINPR_ASSERT and abort the server process.

Title
FreeRDP 3.0.0 before 3.32.2 Denial of Service via Slow-Path Input Event
Summary
FreeRDP 3.0.0 before 3.32.2 server-side RDP peer input parsing skips the six-byte body of a slow-path input event with an unknown message type without checking it lies within the packet's declared length, causing a WinPR stream assertion failure. A remote RDP client with an active session can send a truncated unknown input event to abort assertion-enabled server processes, causing denial of service.

Title
FreeRDP before 3.32.2 Denial of Service via Oversized X.224 Routing Token
Summary
FreeRDP before 3.32.2 contains a denial of service vulnerability that allows malicious servers or unauthenticated peers to abort clients or proxies via oversized X.224 routing tokens. Attackers can send an oversized LoadBalanceInfo in a Server Redirection PDU, or a 240–247 byte token to a FixedTarget freerdp-proxy, triggering a tpdu_write_header assertion that crashes the process.
