A flaw was found in util-linux. Improper hostname canonicalization in the `login(1)` utility, when invoked with the `-h` option, can modify the supplied remote hostname before setting `PAM_RHOST`. A remote attacker could exploit this by providing a specially crafted hostname, potentially bypassing host-based Pluggable Authentication Modules (PAM) access control rules that rely on fully qualified domain names. This could lead to unauthorized access.

A flaw was found in Istio. This vulnerability in Envoy's Role-Based Access Control (RBAC) header matching could allow an attacker to bypass authorization policies. By crafting requests with multiple header values, an attacker could cause Envoy to misinterpret the header, leading to unauthorized access to protected services.

A flaw was found in Istio. A user of Istio could be impacted if the JSON Web Key Set (JWKS) resolver becomes unavailable or fails to fetch keys. This vulnerability can lead to the exposure of hardcoded default settings, potentially bypassing authentication mechanisms and allowing unauthorized access.

A flaw was found in pypdf, a pure-Python PDF library. An attacker can craft a malicious PDF file containing a content stream with an intentionally large /Length value. When this PDF is parsed, it can lead to excessive memory consumption, resulting in a Denial of Service (DoS) condition due to resource exhaustion.

A flaw was found in quinn-proto, a pure-Rust implementation of the IETF QUIC transport protocol. A remote, unauthenticated attacker can trigger a denial of service in applications using vulnerable quinn versions by sending a crafted QUIC Initial packet containing malformed quic_transport_parameters. In quinn-proto parsing logic, attacker-controlled varints are decoded with unwrap(), so truncated encodings cause Err(UnexpectedEnd) and panic. This is reachable over the network with a single packet and no prior trust or authentication.

A flaw was found in file-type, a library for detecting file types. A remote attacker can exploit this by providing a specially crafted ASF (Advanced Systems Format) file. When parsing the file, a zero-sized sub-header can trigger an infinite loop, leading to a Denial of Service (DoS). This can stall the Node.js event loop, preventing the application from processing further requests.

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol (RDP). The `gdi_surface_bits()` function, which processes `SURFACE_BITS_COMMAND` messages, does not properly validate image dimensions (`bmp.width` and `bmp.height`) provided by a malicious RDP server. This can lead to a heap buffer overflow during bitmap decoding and memory operations. A remote attacker could exploit this to overwrite adjacent memory, potentially resulting in arbitrary code execution.

node-tar is a full-featured Tar for Node.js. Prior to version 7.5.11, tar (npm) can be tricked into creating a symlink that points outside the extraction directory by using a drive-relative symlink target such as C:../../../target.txt, which enables file overwrite outside cwd during normal tar.x() extraction. This vulnerability is fixed in 7.5.11.

Buffer overflow in parallel HNSW index build in pgvector 0.6.0 through 0.8.1 allows a database user to leak sensitive data from other relations or crash the database server.

A flaw was found in Keycloak. An administrator with `manage-clients` permission can exploit a misconfiguration where this permission is equivalent to `manage-permissions`. This allows the administrator to escalate privileges and gain control over roles, users, or other administrative functions within the realm. This privilege escalation can occur when admin permissions are enabled at the realm level.

A security flaw was identified in the Orchestrator Plugin of Red Hat Developer Hub (Backstage). The issue occurs due to insufficient input validation in GraphQL query handling. An authenticated user can inject specially crafted input into API requests, which disrupts backend query processing. This results in the entire Backstage application crashing and restarting, leading to a platform-wide Denial of Service (DoS). As a result, legitimate users temporarily lose access to the platform.

A flaw was found in Libsoup. The server-side digest authentication implementation in the SoupAuthDomainDigest class does not properly track issued nonces or enforce the required incrementing nonce-count (nc) attribute. This vulnerability allows a remote attacker to capture a single valid authentication header and replay it repeatedly. Consequently, the attacker can bypass authentication and gain unauthorized access to protected resources, impersonating the legitimate user.

A flaw was found in Sequelize, a Node.js Object-Relational Mapper (ORM) tool. A remote attacker can exploit a SQL injection vulnerability by manipulating JSON object keys during JSON/JSONB where clause processing. This allows for the injection of arbitrary SQL commands due to the improper handling of cast types. The primary consequence is the potential for unauthorized data exfiltration from any database table.

A flaw was found in Flare, a file sharing platform. An authenticated path traversal vulnerability exists in the /api/avatars/[filename] endpoint, allowing a logged-in user to read arbitrary files from the application container. This occurs because the filename parameter is not properly sanitized, enabling specially crafted sequences to bypass directory restrictions. If open registration is enabled, an attacker can self-register and exploit this vulnerability, leading to sensitive information disclosure.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, a 32-bit unsigned integer overflow in the XWD (X Windows) encoder can cause an undersized heap buffer allocation. When writing a extremely large image an out of bounds heap write can occur. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, a crafted image could cause an out of bounds heap write inside the WaveletDenoiseImage method. When processing a crafted image with the -wavelet-denoise operation an out of bounds write can occur. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16, BilateralBlurImage contains a heap buffer over-read caused by an incorrect conversion. When processing a crafted image with the -bilateral-blur operation an out of bounds read can occur. This vulnerability is fixed in 7.1.2-16.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16, a heap-based buffer overflow in the UHDR encoder can happen due to truncation of a value and it would allow an out of bounds write. This vulnerability is fixed in 7.1.2-16.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, MagnifyImage uses a fixed-size stack buffer. When using a specific image it is possible to overflow this buffer and corrupt the stack. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41.

An unbounded recursion flaw has been discovered in the pypi pyasn1 library. This uncontrolled recursion occurs when decoding ASN.1 data with deeply nested structures. An attacker can supply a crafted payload containing nested SEQUENCE (0x30) or SET (0x31) tags with Indefinite Length (0x80) markers. This forces the decoder to recursively call itself until the Python interpreter crashes with a RecursionError or consumes all available memory (OOM), crashing the host application.
