H5Z__filter_nbit in H5Znbit.c in HDF5 through 2.3.0 dereferences cd_values[0] through cd_values[4] without validating that cd_values is non-NULL or that cd_nelmts is at least 5, the fixed size of the filter's header. This allows attackers to cause a denial of service via a crafted HDF5 file that stores the N-Bit filter pipeline message with zero client-data values, opened and read via H5Dread, e.g. by the h5ls or h5repack tools.

CVE-2026-19024——
———NULL pointer dereference in H5Pget_fill_value in HDF5 before 2.1.1 allows attackers to cause a denial of service via a dataset whose version 1 or 2 fill value message has the "defined" flag set together with a negative size field, which is not normalized to the library's "undefined" sentinel and reaches H5T_path_find with a NULL datatype.6hCVE-2026-713147.5 HIG—
———Nuxt is an open-source web development framework for Vue.js. From 3.1.0 until 3.21.10 and 4.5.1, an unauthenticated attacker can use a server island v-for prop, including vforToArray and , to trigger unbounded SSR memory allocation until MAX_VFOR_LENGTH = 100000 and crash the Nuxt process. This issue is fixed in 3.21.10 and 4.5.1.8hCVE-2026-203137.7 HIG—
———As part of Cisco's ongoing commitment to proactive security and product quality, the Cisco Catalyst SD-WAN engineering team has conducted a comprehensive internal security review. This review resulted in software hardening releases that address multiple internally discovered vulnerabilities.
The vulnerabilities tracked by CVE-2026-20313 are related to Improper link resolution before file access issues that are grouped under the Common Weakness Enumeration (CWE) CWE-1284.11hCVE-2026-703787.5 HIG—
——0imagecli's `carve <ratio>` pipeline operation (Carve::apply() in src/image_ops.rs) only asserts `ratio <= 1.0`, never validating that the ratio is positive. A negative ratio (e.g. -5) causes the computed target width to saturate to 0 via Rust's defined float-to-uint cast, which is then passed to imageproc::seam_carving::shrink_width — a function that panics when given a width below 2, crashing the process. This shares the same missing-input-validation root cause as the sibling `scale` finding in the same file but is an independently fixable, distinct code path.15hCVE-2026-46334——
——0OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Versions prior to 3.6.6 and 4.0.0-rc1 contain a denial of service vulnerability in the SDP bandwidth-line parsing logic. A SIP request with Content-Type: application/sdp and a malformed session-level SDP bandwidth line missing the required colon delimiter can corrupt parsed SDP bandwidth metadata. When a route or module subsequently clones the corrupted SDP state, as occurs with dialog and QoS processing, the OpenSIPS worker process crashes. An unauthenticated remote attacker can therefore trigger a crash in any configuration whose routing script parses attacker-controlled SDP and applies dialog/QoS processing. This issue has been fixed in versions 3.6.6 and 4.0.0-rc1.14hCVE-2026-45084——
——0OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Versions 3.4.0 through 3.6.5 contain a denial of service vulnerability in the presence module. When the presence module's handle_publish() function processes a SIP PUBLISH request with an Event: presence header and a message body while the configuration option enable_sphere_check=1 is set, it invokes the get_content_type() macro without first calling parse_content_type_hdr(), causing it to dereference uninitialized or NULL Content-Type parsing state and crash. If a Content-Type header is present but unparsed, msg->content_type->parsed is NULL and is dereferenced as a content_t pointer; if the request lacks a Content-Type header entirely, msg->content_type itself is NULL, and both cases lead to a crash. A remote attacker can therefore cause a denial of service against an affected instance with a single PUBLISH request over UDP or TCP, using either a valid Content-Type: application/pidf+xml request or one with the header removed, and the vulnerable code path itself does not enforce authentication (though a deployment's routing configuration may require it before this route is reached). The issue has been fixed in version 3.6.6 and 4.0.0-rc1.14h
