RHSA-2026:68697
Vulnerability from csaf_redhat - Published: 2026-09-17 15:47 - Updated: 2026-09-22 09:24A flaw was found in SQLite's FTS5 full-text search extension. This vulnerability involves memory corruption, specifically an out-of-bounds read and a heap buffer overflow, which can be triggered by supplying a crafted database with malformed FTS5 page data. When an FTS5 MATCH query is executed against such a database, an attacker can cause process crashes, memory exhaustion, or achieve arbitrary code execution, potentially compromising the system.

A flaw was found in SQLite, specifically within its FTS5 full-text search extension. Attackers can exploit a heap-based buffer overflow by providing a specially crafted database. This crafted database contains malicious metadata that triggers an integer underflow during FTS5 MATCH query processing. Successful exploitation of this vulnerability can lead to a crash of the application or allow for arbitrary code execution.
A flaw was found in Apache Thrift. This vulnerability, categorized as improper handling of highly compressed data (also known as data amplification), allows a remote attacker to cause a Denial of Service (DoS) by sending specially crafted, highly compressed data. The affected component fails to properly manage the expansion of this data, leading to resource exhaustion and system unavailability.
A flaw was found in Apache Thrift's C++, c_glib, Go, netstd, Delphi, and Haxe bindings. This integer overflow or wraparound vulnerability allows a remote attacker to cause a denial of service (DoS) by sending specially crafted input. The flaw can lead to the affected service becoming unavailable.
A heap buffer overflow vulnerability was found in libaom, the reference AV1 codec implementation. A flaw in the AV1 encoder's Look-Ahead Processing (LAP) mode causes the first-pass stats ring buffer wrap-around guard to be bypassed when g_lag_in_frames is set to 1 or higher. This results in a 232-byte out-of-bounds write on every encoded frame after the second, corrupting adjacent heap objects. An attacker who can influence encoder configuration in a transcoding service or WebRTC session could exploit this to cause a denial of service (process crash) or potentially achieve code execution.
An arbitrary address write vulnerability was found in libaom, the reference AV1 codec implementation. A missing bounds check in the SVC (Scalable Video Coding) layer ID control function allows an attacker to inject an arbitrary pointer into the cyclic refresh map field via crafted image pixel values. The encoder then writes approximately 1,200 bytes at the attacker-controlled address. This is fully deterministic and does not require a separate information leak. An attacker who can supply frames to a network-facing libaom encoder with SVC enabled could exploit this for denial of service or potential code execution.
A heap-buffer-overflow read vulnerability was found in libaom, the reference AV1 codec implementation. A missing bounds check in the SVC (Scalable Video Coding) layer ID control function allows setting a spatial_layer_id exceeding the configured number of layers. This causes an out-of-bounds heap read of approximately 40,728 bytes when computing a layer context array index. An attacker who can influence SVC encoder parameters in a network-facing service could exploit this for information disclosure (heap content leak) or denial of service (segmentation fault from hitting unmapped memory).
A remote code execution vulnerability was found in libaom, the reference AV1 codec implementation. Insufficient bounds validation in the AV1 encoder's SVC (Scalable Video Coding) layer ID control allows an attacker to supply crafted video frame pixels that overlap with internal encoder layer context structures. In fork-based video processing services, an attacker can use this to hijack the cyclic refresh map pointer, brute-force the process base address via a crash oracle, and redirect control flow to achieve arbitrary command execution. Exploitation requires the target service to use libaom with SVC encoding enabled and accept attacker-supplied video frames.
A flaw was found in FFmpeg's RASC video decoder. A remote attacker could exploit this by providing a crafted media stream using the RASC FourCC (Four Character Code), which is then decoded by libavcodec. This vulnerability triggers a bitstream-controlled out-of-bounds heap write and an adjacent out-of-bounds read, leading to memory corruption. This can result in a denial of service or potentially arbitrary code execution.
A flaw was found in FFmpeg. A remote attacker could exploit an out-of-bounds memory access vulnerability in the ADX audio decoder by supplying a specially crafted ADX or AAX audio file. This could lead to the attacker triggering both out-of-bounds reads and writes, potentially resulting in arbitrary code execution, information disclosure, or denial of service.
A flaw was found in AIOHTTP, an asynchronous HTTP client/server framework. This vulnerability allows a remote attacker to perform HTTP request smuggling due to an edge case in the WebSocket upgrade procedure. When a WebSocket upgrade request includes a body, the parser may switch protocols before the entire body is received. This leaves trailing data to be processed incorrectly, potentially enabling an attacker to bypass security mechanisms or gain unauthorized access to resources.
A flaw was found in AIOHTTP, an asynchronous HTTP client/server framework. This vulnerability involves an out-of-bounds heap read in the C response parser when processing malformed HTTP responses. An attacker operating a malicious server, or even an accidental malformed response, could exploit this to trigger a Denial of Service (DoS) in the client application, making it unavailable.

"text": "A remote code execution vulnerability was found in libaom, the reference AV1 codec implementation. Insufficient bounds validation in the AV1 encoder\u0027s SVC (Scalable Video Coding) layer ID control allows an attacker to supply crafted video frame pixels that overlap with internal encoder layer context structures. In fork-based video processing services, an attacker can use this to hijack the cyclic refresh map pointer, brute-force the process base address via a crash oracle, and redirect control flow to achieve arbitrary command execution. Exploitation requires the target service to use libaom with SVC encoding enabled and accept attacker-supplied video frames.",

"text": "This vulnerability is rated as Critical severity because the researcher demonstrated successful remote code execution against a fork-based video processing service. The exploit chain leverages attacker-controlled pixel values to hijack internal encoder pointers, uses a crash oracle to brute-force ASLR, and ultimately achieves arbitrary command execution. However, the attack complexity is elevated: it requires a fork-based service architecture (for the crash oracle), multiple encoding attempts (for ASLR brute-force), and knowledge of the target binary layout. In Red Hat products, libaom ships bundled within Firefox and Thunderbird. Firefox does not use a fork-based architecture for WebRTC encoding, and SVC layer parameters are managed internally, making the demonstrated exploit chain not directly applicable to the browser context. RHEL-AI 3.4 (aom 3.12.0) and Hummingbird 1 (aom 3.13.3) ship standalone libaom packages within the affected version range. Fork-based transcoding or video conferencing services that use libaom with SVC encoding and accept attacker-supplied frames are at highest risk for this specific exploit chain.",

An attacker cannot trigger this vulnerability entirely remotely on their own; they must supply a specially crafted ADX or AAX audio file and rely on a user or an automated media-processing system to actively parse it using the FFmpeg library.\n\nImpact Limitations: Although the out-of-bounds read and write vulnerabilities have the potential to allow for arbitrary code execution or information disclosure, achieving this reliably is highly complex and depends on the memory layout and protections of the specific application utilizing FFmpeg. In most typical scenarios, processing the malformed file will simply cause the parsing application to crash, resulting in a localized Denial of Service (DoS) rather than a full system compromise.",
