CVE-2025-2175
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability was found in libzvbi up to 0.2.43. It has been rated as problematic. Affected by this issue is the function _vbi_strndup_iconv. The manipulation leads to integer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 0.2.44 is able to address this issue. It is recommended to upgrade the affected component. The code maintainer was informed beforehand about the issues. She reacted very fast and highly professional.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisA legacy NVD category grouping numeric mistakes — overflows, truncation, sign errors — where a miscalculated value goes on to drive a dangerous decision such as a memory allocation or a bounds check. It is a bucket rather than one specific bug. Remediation is checked arithmetic and validating any computed size or index before it is used.

0.2.44
- Identify the current installed version of Zvbi/libzvbi using your system's package manager or by checking the library version
- For source-based installations: download Zvbi version 0.2.44 from the official source (e.g., https://github.com/zapping-vbi/zvbi/releases)
- Recompile and reinstall the library according to the project's build instructions (typically ./configure && make && make install)
- For package-managed systems: check if your distribution has released version 0.2.44 and upgrade via the appropriate package manager (e.g., apt, yum, dnf, brew)
- Rebuild any applications that link against libzvbi to ensure they use the updated library
- Verify the upgrade was successful by checking the library version matches 0.2.44 or later
