pypdf: Possible large memory usage for wrong image dimensions

pypdf is a free and open-source pure-python PDF library. Prior to 6.14.0, an attacker can craft a PDF with declared image size values that are much too large compared to the actual data, causing large memory usage in pypdf image parsing. This issue is fixed in version 6.14.0.

pypdf: Possible large memory usage for form XObjects during text extraction

pypdf is a free and open-source pure-python PDF library. Prior to 6.12.2, an attacker who uses this vulnerability can craft a PDF which leads to large memory usage. This requires extracting the text of a page which contains a form XObject with self-references. This vulnerability is fixed in 6.12.2.

Quadratic runtime with malformed PDF missing xref marker in pypdf

pypdf is a pure-python PDF library capable of splitting, merging, cropping, and transforming the pages of PDF files. An attacker who uses this vulnerability can craft a PDF which leads to unexpected long runtime. This quadratic runtime blocks the current process and can utilize a single core of the CPU by 100%. It does not affect memory usage. This issue has been addressed in PR 808 and versions from 1.27.9 include this fix. Users are advised to upgrade. There are no known workarounds for this vulnerability.

pypdf is a free and open-source pure-python PDF library. Prior to 6.13.0, an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires extracting the text in layout mode. This vulnerability is fixed in 6.13.0.

pypdf: Possible infinite loop when processing threads/articles in writer

pypdf is a free and open-source pure-python PDF library. Prior to 6.13.1, an attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires merging a file with threads/articles into a writer. This vulnerability is fixed in 6.13.1.

Corosync: corosync: heap-based buffer overflow in totempg assembly buffer during fragmented message reassembly

A heap-based buffer overflow was found in Corosync's Totem Process Group (totempg) message reassembly. When processing fragmented multicast messages, the buffer used to reassemble fragments lacks a runtime bounds check in release builds. A network-adjacent attacker able to send crafted multicast protocol messages to the cluster could cause a heap buffer overflow with attacker-controlled data. This can crash the Corosync daemon, causing a denial of service to the entire cluster, and may potentially allow further exploitation given sufficient heap-corruption control.

A buffer overflow issue was addressed with improved memory handling. This issue is fixed in iOS 26.7.2 and iPadOS 26.7.2, iOS 27.2 and iPadOS 27.2, macOS Golden Gate 27.2, macOS Sequoia 15.8.2, macOS Tahoe 26.7.2, tvOS 27.2, visionOS 27.2, watchOS 27.2.

Memory Corruption Exploitable via Malicious File Parsing on Apple Platforms

A memory corruption issue was addressed with improved memory handling. This issue is fixed in iOS 26.7 and iPadOS 26.7, iOS 27.2 and iPadOS 27.2, macOS Golden Gate 27.2, macOS Sequoia 15.8.2, macOS Tahoe 26.7.2. Parsing a file may lead to an unexpected app termination or arbitrary code execution.

Unauthenticated Sensitive Information Disclosure leads to Remote Code Execution in AOS-10

Sensitive information disclosure vulnerabilities in the affected interface of AOS-10 could allow an unauthenticated remote attacker to obtain sensitive information from the affected system. Successful exploitation could allow an attacker to execute arbitrary commands on the underlying operating system.

Type Confusion Vulnerability in iOS/iPadOS Enables Access to Sensitive User Data

A type confusion issue was addressed with improved checks. This issue is fixed in iOS 27.2 and iPadOS 27.2. An app may be able to access sensitive user data.

Authorization Flaw Allows Sensitive Data Access Across Apple Operating Systems

An authorization issue was addressed with improved state management. This issue is fixed in iOS 26.7.2 and iPadOS 26.7.2, iOS 27.2 and iPadOS 27.2, macOS Golden Gate 27.2, macOS Sequoia 15.8.2, macOS Tahoe 26.7.2, visionOS 27.2, watchOS 27.2. An app may be able to access sensitive user data.

Dify 1.9.1 and 1.17.0 exposes the /console/api/system-features endpoint to unauthenticated HTTP GET requests that return system feature and configuration information. NOTE: The maintainer states that the endpoint is unauthenticated by design and serves as a bootstrap mechanism required for the dashboard initialization. They also state that the data is non-sensitive and required for client-side rendering. No PII, credentials, or secrets are exposed.

Privilege Escalation via Protection Mechanism Failure in LLM Scaler Software

Protection mechanism failure for some LLM Scaler software within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with a privileged user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires passive user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
