Title
Nbdkit: nbdkit-server: off-by-one error when processing block status may lead to a denial of service
Summary
There's a flaw in the nbdkit server when handling responses from its plugins regarding the status of data blocks. If a client makes a specific request for a very large data range, and a plugin responds with an even larger single block, the nbdkit server can encounter a critical internal error, leading to a denial-of-service.

CVE-2025-53014 (GCVE-0-2025-53014)

Title
ImageMagick has Heap Buffer Overflow in InterpretImageFilename
Summary
ImageMagick is free and open-source software used for editing and manipulating digital images. Versions prior to 7.1.2-0 and 6.9.13-26 have a heap buffer overflow in the `InterpretImageFilename` function. The issue stems from an off-by-one error that causes out-of-bounds memory access when processing format strings containing consecutive percent signs (`%%`). Versions 7.1.2-0 and 6.9.13-26 fix the issue.

CVE-2026-12413 (GCVE-0-2026-12413)

Vulnerability from cvelistv5 – Published: 2026-07-02 21:19 – Updated: 2026-07-07 17:02
VLAI
Title
IKEv2 Denial of Service via malformed fragmentation
Summary
An invalidly formatted IKEv2 fragment causes the Libreswan pluto daemon to crash and restart. Continued exploitation would cause a denial of service. The function reassemble_v2_incoming_fragments() would ignore unknown outer payloads but still store these in a fixed size array msg_digest.digest[PAYLIMIT]. An off-by-one error in the assertion PASSERT(logger, md->digest_roof < elemsof(md->digest)) causes the daemon to abort. No remote code execution is possible. Any configuration that allows IKEv2 connections that do not set fragmentation=no are vulnerable. IKEv1 is not affected.

Mitigation

Phase: Implementation

Description:

  • When copying character arrays or using character manipulation methods, the correct size parameter must be used to account for the null terminator that needs to be added at the end of the array. Some examples of functions susceptible to this weakness in C include strcpy(), strncpy(), strcat(), strncat(), printf(), sprintf(), scanf() and sscanf().
