Summary
zvbi security update
Details

The ZVBI library provides functions to read from Linux V4L, V4L2 and FreeBSD BKTR raw VBI capture devices, from Linux DVB devices and from a VBI proxy to share V4L and V4L2 VBI devices between multiple applications. It can demodulate raw to sliced VBI data in software, with support for a wide range of formats, has functions to decode several popular services including Teletext and Closed Caption, a Teletext cache with search function, various text export and rendering functions.

Security Fix(es):

A vulnerability was found in libzvbi up to 0.2.43. It has been declared as problematic. Affected by this vulnerability is the function vbi_strndup_iconv_ucs2 of the file src/conv.c. The manipulation of the argument src_length leads to integer overflow. The attack can 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. The patch is named ca1672134b3e2962cd392212c73f44f8f4cb489f. It is recommended to upgrade the affected component. The code maintainer was informed beforehand about the issues. She reacted very fast and highly professional.(CVE-2025-2174)
