Descrição técnica

Lib/ipaddress.py in Python through 3.8.3 improperly computes hash values in the IPv4Interface and IPv6Interface classes, which might allow a remote attacker to cause a denial of service if an application is affected by the performance of a dictionary containing IPv4Interface or IPv6Interface objects, and this attacker can cause many dictionary entries to be created. This is fixed in: v3.5.10, v3.5.10rc1; v3.6.12; v3.7.9; v3.8.4, v3.8.4rc1, v3.8.5, v3.8.6, v3.8.6rc1; v3.9.0, v3.9.0b4, v3.9.0b5, v3.9.0rc1, v3.9.0rc2.

——0Dell Live Optics Collector, versions prior to 27.3.8.317 contains a Use of Insufficiently Random Values vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Information exposure.20h CVE-2026-1153366.5 MÉD

——8Incorrect quota accounting in Progress Software WS_FTP Server releases prior to 2025.0.5 on Windows could allow an authenticated user with upload and delete permissions to exceed storage quotas, potentially causing denial of service.3d CVE-2026-946185.4 MÉD

——3FileGator is a multi-user file manager. Prior to 7.15.0, GET /batchdownload in backend/Controllers/DownloadController.php uses batchDownloadStart() to stream a shared temporary archive selected by the request-supplied uniqid without checking that the current session created it. In deployments with distinct per-user home directories, a valid user with read, download, and batchdownload permissions who obtains another user's active archive id can cross that boundary and retrieve the victim's batch archive. The archive lifetime and id-acquisition requirement limit exploitation, but a successful replay also deletes the victim's pending archive. This issue is fixed in version 7.15.0.2d CVE-2026-487059.3 CRÍ

——13MONAI (Medical Open Network for AI) is an AI toolkit for health care imaging. Prior to 1.6.1, PydicomReader._get_affine() trusts non-finite values in the DICOM PixelSpacing, ImagePositionPatient, and ImageOrientationPatient fields and composes them into an affine matrix without validation. An unauthenticated attacker who can upload a crafted DICOM to a default MONAILabel deployment can propagate NaN or infinity values through LoadImaged, Spacingd, model inference, and output writing, causing inference failures, persistent datastore poisoning, or geometrically corrupted results. This issue is fixed in version 1.6.1.7d CVE-2026-870434.8 MÉD

——2The entropy-device random number generator in subsys/random/random_entropy_device.c returned early with -ENODEV from rand_get() as soon as device_is_ready() failed, before reaching the non-cryptographic system-timer fallback further down the same function. Because z_impl_sys_rand_get() returns void and discards that error — and the public sys_rand_get() syscall is itself declared void, so it cannot report failure — the caller's output buffer was left untouched and its previous contents were handed back as random data. The thin wrappers make this a plain uninitialized read: sys_rand32_get() declares uint32_t ret;, calls sys_rand_get(&ret, sizeof(ret)) and returns ret. The "not ready" state is a normal runtime condition rather than a fault. Entropy drivers initialise at PRE_KERNEL_1 with CONFIG_ENTROPY_INIT_PRIORITY (default 50), so any earlier initialiser — kernel objects run at priority 30 — observes an unready device; the sibling generator subsys/random/random_xoshiro128.c and z_early_rand_get() in kernel/init.c both already carried an explicit timer fallback for exactly this case. The state is also permanent for the boot when an entropy driver's init hook fails, which several in-tree drivers can do on real hardware (entropy_stm32 on an RNG clock configuration error, entropy_psa_crypto when psa_crypto_init() fails, entropy_nrf_cracen, entropy_esp32, entropy_virtio). When this occurs, every non-cryptographic random value in the system is either a constant or stale memory. coap_next_token() in subsys/net/lib/coap/coap.c fills a static buffer, so every CoAP token becomes the same .bss constant; tcp_init_isn() in subsys/net/ip/tcp.c returns an uninitialized stack word as the TCP initial sequence number; DHCPv4/DHCPv6 transaction IDs, WebSocket masking keys and RTP SSRCs are similarly degraded, and arch/arm64/core/pac.c derives per-thread Pointer Authentication keys from the same source. Where the bytes are transmitted directly — SSH packet padding, the netmidi2 session nonce, a DTLS connection ID on builds without CONFIG_CSPRNG_ENABLED — stale caller stack or heap contents are disclosed on the wire. The fix initialises ret to -ENODEV and only calls entropy_get_entropy() when the device is ready, so the not-ready case now falls through to the timer fallback and the buffer is always written. The cryptographically secure path is unchanged: sys_csrand_get() still propagates the error to the caller and never silently degrades. An attacker cannot induce the unready state, but can observe and exploit the resulting non-random values remotely on an affected device.3d CVE-2026-1202233.1 BAI

——7A vulnerability was identified in Oray Pugongying X5 Pro up to 7.6.1. This impacts the function session_get of the file session.lua of the component Session ID Handler. The manipulation of the argument _user leads to insufficiently random values. The attack can be initiated remotely. The attack's complexity is rated as high. The exploitability is said to be difficult. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.10d
